Changes:
* 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). This code
will be expanded on and optimized in future releases.

* Adding editing of extended RAM in the debugger RAM UI. The RAM
´spreadsheet´ now shows the entire address space of RAM in the
system, in 128 byte increments. The first bank shown is zero-page,
with the others following in consecutive order. The UI takes care
of read vs. write port differences, so you don´t have to worry
about the offsets. For now, all SuperChip based ROMs (EFSC, F4SC,
F6SC, F8SC) as well as 3E, CV, E7 and FASC are supported.

* All ROMs 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.

* Visual improvements to the CPU register UI in the debugger; the
SP/A/X/Y registers now have separate decimal and binary views.

* Tweaked paddle control so that all positions are reachable in game
4 of Activision Casino in both NTSC and PAL versions.

* SuperCharger/AR ROMs now start with a random value in the CPU
accumulator. This should fix issues with Dragonstomper always
starting in exactly the same state.

* Auto-detection for ´3F´ bankswitching improved; several ROMs
previously detected as ´F8´ now work correctly.

* Updated internal ROM properties database to ROM-Hunter version 5
(thanks go to RomHunter for his tireless research in this area).

* Added ´-exitlauncher´ commandline argument and associated UI item,
to specify what happens when you exit a ROM. Normally, exiting a
ROM brings up the ROM launcher, but this can be disabled for those
using an external frontend (in which case exiting a ROM also exits
from Stella).

* Re-added ´-fastscbios´ commandline argument, and added an associated
UI item. When enabled, the SuperCharger load bars are now completely
removed (and not just sped up as in previous releases).

* The ´-listrominfo´ commandline argument now shows all ROM
information built in to the internal database, taking into account
any information in ´personal´ stella.pro files.
