Lowered utorrent args by 1. remove uselink test

Since we don't pass sys.argv[1] as 'utorrent' we need to reduce the input arg numbers by 1.
We can't (as I understand) test for useLink here unless we pass it in... so let's just set up utorrentClass anyway and test for uselink back in TorrentToMedia.py
also added try, except as this can cause issues if these parameters are not passed in... maybe a bit unnecessary, but doesn't hurt.
