Spoike 1bb752b582 sdl2 support. 
hacky rendertarget stuff. not polished. don't use except for testing. feedback desired.
switched file system to use a qofs_t type instead. define FS_64BIT to make it 64bit (standard on 64bit cpus).
rewrote zip support, ditching unzip.c. this provided zip64 support, and unicode in zips.
changed local address enumeration to not be so stupid.
updated ode support a little to match some dp features.
changed fs_cache scheme, to not rebuild needlessly.
