Changelog:
* Game Boy (Color): STAT OAM+HBlank IRQs only trigger during LY=0-143 with display enabled
** fixes backgrounds and text in Wacky Races
* Game Boy (Color): fixed underflow in window clamping
** fixes Wacky Races, Prehistorik Man, Alleyway, etc
* Game Boy (Color): LCD OAM DMA was running too slow
** fixes Shin Megami Tensei - Devichil - Kuro no Sho
* Game Boy Advance: removed built-in frame blending; display emulation shaders will handle this going forward
* Game Boy Advance: added Game Boy Player emulation
** currently the screen is tinted red during rumble, no actual gamepad rumble support yet
** this is going to be slow, as we have to hash the frame to detect the GBP logo, it´ll be optional later on
* Emulator::Interface::Palette can now output a raw palette (for Display Emulation shaders only)

I´m able to load slot games here, so if you still have issues please don´t report that unless you have a fix, thanks =)
