Add Blargg's "blip_buf" as an unmanaged dll. license is LGPL; if I like the way it works, I'll rewrite it with MIT code. Implement it as the new resampling output track for NES. Small (~3%)? speedup. Should sound better, especially when the emulator can't quite keep speed.

Add unmanaged version of 6502X core. The core it self is nearly exactly a copy+paste job from the C# one; most things map over exactly. A strange and abusive p/invoke setup is required to realize a performance gain; see code for details. Seems to be worth a bit more than 20% overall speed for me. Core is savestate compatible with managed 6502X. slight modifications to existing API has been made to support the new cpu. also included is a test module that runs both cores together, savestating every cycle to check for sameness. Core should fit in Atari, although that hasn't been done yet. For the moment, tracelog and disassemble are broken, but they'll be back soon.

nes-unif support. we will need to explicitly add every UNIF board we support to their respective mappers, because
...
[1] each unif board name carries with it its own unique assumptions about which chips are present.
[2] the unif board names may not be matching bootgod's, which we accept as canonical;
also fix a small memory leak due to nes boards not being disposed during scan process.

nes-fix dmc sfx bug in bt&dd making nonexistent sfx; add emulation of empty databus (to extra joystick bits and reads of nonexistent EXP and WRAM memory ranges.. need to scan other emulator source codes for places to check for use of empty databus); fixes freeze bug in bt&dd. also break savestates, but add a crude version system so we at least have a way to avoid it in the future.
...
bt&dd has a glitch that reads from $6000 when there is no ram installed, and crashes if something too large is returned. I think this chooses a frame for abobo, and you can actually see abobo's sprites glitch for one frame right when the wall finishes getting busted down (the same place where bizhawk was freezing)

add 'bool rendersound' to IEmualtor.FrameAdvance()
...
if false, the emulator is free to gain whatever speedup it can by not doing audio processing (shouldn't change anything sync related, though)
the core should still always call SoundProvider.GetSamples() after each FrameAdvance(), else DRAGONS
at the moment, only test-implemented in gambattehawk

add CoreInputComm.CpuTraceEnable and CoreInputComm.CpuTraceStream, and use it in NES; set those appropriately from a gui component and you can effect user-controlled cpu tracing, if its been setup in the core he's interested in. CoreInputComm doesnt reconstruct between emulator instances, so this may not be the best way of hooking it up, but its serviceable.

NES - implement address poking on the system bus domain. Anything in the EXP, WRAM, PRG regions is done via the built in cheat system due to being handled by the mappers. This may not be the ideal way to do this but it seems to work well, and I don't know of a more logical way to handle this.
