[3DS] Vice3DS v1.3

Badda has released a Commodore 64 emulator to the Nintendo 3DS:

This is a port of the VICE C64 emulator to 3DS.
VICE - the Versatile Commodore Emulator - http://vice-emu.sourceforge.net/

@spinal_cord made a C64 emulator (Breadbox) based on Frodo but it does not work anymore with recent firmwares and he is not updating it anymore, so I gave it a shot to port the Vice C64 emulator v3.3 to the 3DS. Vice does support SDL1 but porting was not quite as easy as "just compile": A new sounddriver for the 3DS needed to be written, devkitpro libraries do not support all functionality required by full fledged Vice (so I had to strip them in quite some places) and lots of other things that needed tweaking or adaption.
The result is: Vice3DS
