Bug#811214: RFS: retroarch/1.3.0-1 [ITP]

[Sérgio Benjamim]

RetroArch is in the new queue! Thanks Gianfranco!

I updated some of the libretro cores, for mupen64plus and beetle-psx 
it's better to stick with the old ones (not so old...). Lot of commits 
nowadays, it's better to wait them stay calm.
