Added RomM to Miscellaneous section

Added the RomM retro game library manager to Miscellaneous. RomM allows basic game file management, pulling in metadata from IGDB, with more file management features on the roadmap. Note that RomM itself has no dependencies out of the user's control, but its use of the IGDB database requires a Twitch account.
