DCFilter: allow variable filterwidth. 2600 tia: use a rather aggressive (~172hz cutoff) dc filter. this coefficient is reasonably close to actual hardware behavior.

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

Atari M6532: Turned the timer into an object, and now uses a prescaler, replacing the previous 32 bit int implementation.
...
Fixed a typo with the interrupt flag.
These changes fix freezes with "Berzerk (1982) (Atari)" and "Omega Race (1983) (CBS Electronics)"

Atari 2600: Modified how memory read/writes are handled, to better emulate the address bus. Cleaned up some comments. Turned off CPU debugging. Added functions to read console switches and player 2 buttons.
...
M6532: Mostly re-written, this time based on the datasheet.
TIA: Removed console debug outputs.

Switched over to using the 6507 to allow for some modifications to the CPU
...
MOS6507: now executes instructions on the last cycle. This corrects a syncing issue with the TIA
TIA: added ball data, partially implemented HMOVE, implemented VBLANK

Started work on Atari 2600 core. Added stubs for the TIA and M6532 to be filled in later. Memory map is hard coded, but will only work for basic 4K carts like pitfall. That'll have to be changed later.
