add ability to change api ports in bat file
Through my experimenting, I have found that running nemosminer in multiple sessions (one for each card) staggered ,each with a 15 minute cycle time, is the most profitable way to run it.  That way you get your share percentage up all the way per algo, and you dont loose out on another algo if it goes most profitable.   I have doubled my daily usd by doing this. However it is irritating to edit each miners ps1 file each time a new version comes out.  I propose being able to change the api ports used via the bat file to make it easier.  that way someone unable to figure out how to edit the ps1 file properly can do this, and so that I dont have to have several full nemosminer folders configured.
