Added preliminary support for the following libretro cores: mame_libretro.dll
Note that currently this core has limited compatibility. Low-end games will work best.
Fixed an issue that caused joypad input to be sent more than once to libretro.
Adjusted downloading of assets from MP servers. Now only the workshop map and workshop save that you are using will be downloaded from the workshop.
Additional objects from other workshop items that you have spawned in your arcade are no longer downloaded from the workshop, but from the MP server.
This fixes the issue of people having to download a 200MB workshop item just because you spawned a single prop from it.
Added the file "aarcade/cores/libretroCorePriorities.txt" for any advanced users who want to try out additional libretro cores.
