Script to welcome new users.

This script works out of the box for Wikis that
have been defined in the script. It is currently used on the Dutch, Norwegian,
Albanian, Italian Wikipedia, Wikimedia Commons and English Wikiquote.

Ensure you have community support before running this bot!

Everything that needs customisation to support additional projects is
indicated by comments.

Description of basic functionality

 * Request a list of new users every period (default: 3600 seconds)
   You can choose to break the script after the first check (see arguments)
 * Check if new user has passed a threshold for a number of edits
   (default: 1 edit)
 * Optional: check username for bad words in the username or if the username
   consists solely of numbers; log this somewhere on the wiki (default: False)
   Update: Added a whitelist (explanation below).
 * If user has made enough edits (it can be also 0), check if user has an empty
   talk page
 * If user has an empty talk page, add a welcome message.
 * Optional: Once the set number of users have been welcomed, add this to the
   configured log page, one for each day (default: True)
 * If no log page exists, create a header for the log page first.

This script (by default not yet implemented) uses two templates that need to
be on the local wiki

* {{WLE}}: contains mark up code for log entries (just copy it from Commons)
* {{welcome}}: contains the information for new users

This script understands the following command-line arguments:

   -edit[:#]       Define how many edits a new user needs to be welcomed
                   (default: 1, max: 50)

   -time[:#]       Define how many seconds the bot sleeps before restart
                   (default: 3600)

   -break          Use it if you don't want that the Bot restart at the end
                   (it will break) (default: False)

   -nlog           Use this parameter if you do not want the bot to log all
                   welcomed users (default: False)

   -limit[:#]      Use this parameter to define how may users should be
                   checked (default:50)

   -offset[:TIME]  Skip the latest new users (those newer than TIME)
                   to give interactive users a chance to welcome the
                   new users (default: now)
                   Timezone is the server timezone, GMT for Wikimedia
                   TIME format : yyyymmddhhmmss or yyyymmdd

   -timeoffset[:#] Skip the latest new users, accounts newer than
                   # minutes

   -numberlog[:#]  The number of users to welcome before refreshing the
                   welcome log (default: 4)

   -filter         Enable the username checks for bad names (default: False)

   -ask            Use this parameter if you want to confirm each possible
                   bad username (default: False)

   -random         Use a random signature, taking the signatures from a wiki
                   page (for instruction, see below).

   -file[:#]       Use a file instead of a wikipage to take the random sign.
                   If you use this parameter, you don't need to use -random.

   -sign           Use one signature from command line instead of the default

   -savedata       This feature saves the random signature index to allow to
                   continue to welcome with the last signature used.

   -sul            Welcome the auto-created users (default: False)

   -quiet          Prevents users without contributions are displayed

********************************* GUIDE ***********************************

*** Report, Bad and white list guide: ***

1)  Set in the code which page it will use to load the badword, the
    whitelist and the report
2)  In these page you have to add a "tuple" with the names that you want to
    add in the two list. For example: ('cat', 'mouse', 'dog')
    You can write also other text in the page, it will work without problem.
3)  What will do the two pages? Well, the Bot will check if a badword is in
    the username and set the "warning" as True. Then the Bot check if a word
    of the whitelist is in the username. If yes it remove the word and
    recheck in the bad word list to see if there are other badword in the
    username.
    Example

        * dio is a badword
        * Claudio is a normal name
        * The username is "Claudio90 fuck!"
        * The Bot finds dio and sets "warning"
        * The Bot finds Claudio and sets "ok"
        * The Bot finds fuck at the end and sets "warning"
        * Result: The username is reported.
4)  When a user is reported you have to check him and do

        * If he's ok, put the {{welcome}}
        * If he's not, block him
        * You can decide to put a "you are blocked, change another username"
          template or not.
        * Delete the username from the page.

        IMPORTANT : The Bot check the user in this order

            * Search if he has a talkpage (if yes, skip)
            * Search if he's blocked, if yes he will be skipped
            * Search if he's in the report page, if yes he will be skipped
            * If no, he will be reported.

*** Random signature guide: ***

Some welcomed users will answer to the one who has signed the welcome message.
When you welcome many new users, you might be overwhelmed with such answers.
Therefore you can define usernames of other users who are willing to receive
some of these messages from newbies.

1) Set the page that the bot will load
2) Add the signatures in this way:

    *<SPACE>SIGNATURE
    <NEW LINE>

Example of signatures:

 <pre>
 * [[User:Filnik|Filnik]]
 * [[User:Rock|Rock]]
 </pre>

NOTE: The white space and <pre></pre> aren't required but I suggest you to
      use them.

******************************** Badwords **********************************

The list of Badwords of the code is opened. If you think that a word is
international and it must be blocked in all the projects feel free to add it.
If also you think that a word isn't so international, feel free to delete it.

However, there is a dinamic-wikipage to load that badwords of your project or
you can add them directly in the source code that you are using without adding
or deleting.

Some words, like "Administrator" or "Dio" (God in italian) or "Jimbo" aren't
badwords at all but can be used for some bad-nickname.
