v1.2

Following up on some issues from last year (sorry for the wait!) plus a few other tweaks:

• Added support for RAR and 7z archives
• Added Create Letter Folders option, which allows you to export roms to a folder named after the first letter of the game (if Create Game Folder for Each Game is enabled) or rom
• Improved DAT auto-detection so you shouldn't have to manually input DATs downloaded from the DAT-o-MATIC under most circumstances
• Added Help button that links to the DAT-o-MATIC and updated DAT instructions
• Migrated from cxFreeze to PyInstaller

Enjoy!
