* add MAME to OpenAdvanced
* make mame launch games
limited to arcades that only need rom name. other devices require machine name and rom name, and won't run. nor they are meant to be supported anyway: we have enough emulators that do the job better for particular devices.
dunno if direct disk access will be avoidable, there are quite some files it might want to load other than the rom (parent rom, bios, artwork). trapping all of these might be a future task.
it is also known that mame can load "romname.zip" file just as well as "romname" folder, which would represent an unarchived zip. I make use of it to send it zip name with extension. it's easy, and we're not obliged to recognize mere folder paths in the mame-advanced-loader logic.
* ability to run lua code inside mame
Convertion has been moved to dedicated class
SystemInfo class review
SystemInfo class now instanciate all SystemInfo and stores them in a
static readonly collection (avoid creating a new class each time we call
DisplayName property).
+ EmulatedSystem enum (in Api) renamed to CoreSystem and moved to
BizHawk.Client.Common
+ this enum is used in SystemInfo class
Created a Joypad class that is populated with JoypadButton enum flags
Input get/set throught ApiHawk works for NES only. So many work remains...
