Allow multiple folders for one handler about romniscience HOT 1 OPEN

For reference, these are the handlers (including CD-based ones that I'm going to implement sooner rather than later) that sort of go together and so you might reasonably expect a user to keep them in the same folder, but maybe they might not and so at the moment they'd have to be separate:

GBA + e-Reader
Atari Jaguar + (Jaguar CD)
MSX + MSX2
PC Engine + (Turbografx-CD)
Megadrive + 32X + (Mega CD) + arguably Pico
Game Gear + Master System (kinda? Nearly same hardware, and all emulators that can do one can do the other)
Wii + WiiWare + (Wii homebrew) (maybe Gamecube as well? I'm sure there are people who have a single "Dolphin folder")

PC Engine and Game Boy are two handlers in particular where this issue could become an issue, because maybe people like to put their Supergrafx and GBC ROMs in a different place. Also N64 where I've included N64DD, come to think of it.

Heck, maybe people like to have different regions in a different folder. There's probably people who have a SNES folder and a Super Famicom folder. Who knows.

For what it's worth, you can set two handlers to the same folder, but it might not be obvious to the end user that you can do that, and so maybe they assume you can't, because there's a lot of software out there that asks you for multiple folders and complains when you use the same folder twice for different things.
