Updater 3.1a

-updatebatch now will (or at least should):
*Download new batch and name it [updater]*.bat
*Open that script in a new CMD window.
*Exit

The [updated]*.bat script should:
*Copy itself overwriting the original batch (without renaming).
*Start that script in a new CMD instance.
*Exit.

The new script, with the original name, should:
*Delete the [updated]*.bat script
*Begin the normal script routine.

@earthing do you think I should still rename the scripts to .old or something before overwriting/deleting?
