Changes:

supposed to be 0.5.0. x_x
CORE: Removed x86 optimized core since it's benefits these days are questionable compared to the overhead it induces.
GUI: GUI overhaul, partial Unicode support, and more.
GUI: Added GUI toggle for Zapper emulation.
GUI: Changed default GUI theme to 'Panta'.

VIDEO: Added new DES and DESii blitters.
VIDEO: Added makeshift support for HQ2X, HQ3X, and HQ4X.
VIDEO: Changed default display mode under windowed environments from fullscreen to windowed; use a platform-specific driver
or the 'Force Fullscreen' option to override.
