Okay, let's try this again.
* Moved Impossible Mission to correct location in softlist
* Added 4AM original WOZ images up to Feb 7th, 2019
* Split apple2.xml into apple2_flop_clcracked.xml and apple2_flop_misc.xml
* Changes Apple 2 drivers to support the split softlists. Note there's no compatibility metadata for the older content, so we can't easily filter to the machine type there.
Remaining to be done:
* Sort the clean cracks list alphabetically
* Add 2000+ remaining 4AM clean cracks
I've gone over this PR about three times before commiting on my side just to make sure I didn't miss any major issues, including -valid checks.
