MultiMC support

[forkiesassds]

I use a 3rd party Minecraft launcher (MultiMC) which does not use the typical structure the Minecraft launcher uses, instead of profiles MultiMC uses instances, all versions are stored in a central folder (libraries\com\mojang\minecraft), and libraries are stored at the central libraries folder (libraries), and it does not use launcher_profiles.json

Amidst doesn't support custom launchers, exactly for the reasons you gave: the folder structure isn't the same as the official Launcher.
