added a couple of command line parameters to make it easier to embed LOOT:
- gamePath: manually sets the path to the game instead of having it automatically discovered
- unattended: start sorting immediately without displaying a menu
- skipUpdateMasterlist: don't update the masterlist
- stdout: send all log messages to stdout as well
- noreport: don't open the report at the end. Instead, a line will be printed to the log specifying its location
