OK, this is a BIG commit. 

Added CRT simulation as described by Ian Bogost in the AtariAge thread
'CRT simulation for Stella.  This is just the first pass, but things
are working nicely so far (for those systems that can support it).  It
requires at least OpenGL 2.0 with GLSL (GL Shading language).  Added
the commandline arugments 'tv_tex', 'tv_bleed', 'tv_noise' and 'tv_phos'
used to set these various effects, as well as the ability to set them
within the Video Settings dialog.  More documentation is forthcoming
on this.

All bankswitch modes that use SC RAM now act correctly when reading
from the write port (the RAM is erased).

Patching ROMs with bankswitch type 0840, SB, UA and X07 is now working.

Went through all the bankswitch classes and converted multiplication/
division to shift operations whenever possible.  It's a
micro-optimization, but what the heck; every little bit of speed counts.

Release History
===============================================================================
2.7.7 to 2.8: (June xx, 2009)
* Added CRT simulation effects as described in the AtariAge posting
'CRT emulation for Stella'. For now, this requires OpenGL 2.0 or
greater with support for GLSL (GL Shading Language).
* All bankswitching schemes which include SC extended RAM will now have
memory erased if you attempt to read from the write port. Related to
this, entering/exiting the debugger will no longer erase the extended
RAM.
* Patching of ROM for bankswitch types '0840', 'SB', 'UA' and 'X07' is
now implemented, but hasn't been extensively tested.

2.7.6 to 2.7.7: (May 1, 2009)
* Corrected emulation of CPU opcodes involving 'decimal' mode (ADC/RRA
@ -24,8 +41,6 @@
* Changed internal sound frequency of Pitfall 2 from 15.75KHz to 20KHz,
as this sounds much more authentic when compared to a real cartridge.
