MAME Importing - System Name (Potentially a menu item)

[Brad Cheyne]

Arcade importing has been predicated on the Emulator name being MAME and not the system name all this time. Importing for RetroArch breaks and you are forced to check the box instead of automatically getting the MAME Import screen.

Set up a rule for auto-detecting the system name as well: Arcade, MAME, Triforce, Naomi, Neo Geo etc.

Also, potentially setting up a MAME / Arcade menu item that opens up so you can import all types of Arcade games. Regular MAME (like normal), but then Triforce, NeoGeo, etc. For those who use standalone emulators.
