skpm help command is not working
When running `skpm`, you get a message like this:

```
For help with a specific command, enter:
  skpm help [command]
```

but it turns out that `skpm help [command]` does not work at all, and you get an error message like this:

```
Unknown argument: help
```

If you switch the arguments (i.e: `skpm create help`), it does work.

We should either fix the behaviour, or fix the docs : )
