Changes :

* Greatly improved cartridge bankswitch type auto-detection. Stella
can now (mostly) autodetect cartridge types ´E0´, ´E7´, ´3E´, ´3F´ and
Superchip carts. Obviously, this autodetection is not infallible, but
relies on patterns in the ROM data, and how it was compiled. Because
of the auto-detection types already supported, almost all bankswitch
info was removed from internal ROM properties. Set the ROM property
"Cartridge.Type" to "Auto-detect" for this to take effect.

* Added auto-detection of display type (NTSC or PAL). Currently, PAL60
ROMs will be detected as NTSC. This is almost 100% accurate, and fails
in very few cases (for those that are mislabeled, the ROM properties
can be set specifically). Set the ROM property "Display.Format" to
"Auto-detect" for this to take effect.

* Improved emulation timing when exiting one ROM and starting another.
Previously, this could result in the second ROM having its sound start
later than it should have.

* Removed pause functionality from the core, since it´s been superceded
by the other event states. You can now enter one of the menus for a
similar effect (options, command, debugger, etc).

* Added toggle for PAL color-loss emulation, which defaults to off.
Previous versions of Stella always used color-loss emulation.
Related to this, added ´colorloss´ commandline argument.

* Added rudimentary support for configuring the UI palette (´uipalette´
commandline argument) and ability to change the size of the launcher window
(´launchersize´ commandline argument). This will be expanded on in future
releases.

* Reworked options menu so it´s now accessible from the ROM launcher as
well as while playing a ROM.

* Re-added ability to change the width and height of a Console. Related to
this, changing XStart/YStart/Width/Height dynamically no longer resets
the ROM.

* Removed ´tiadefaults´ commandline argument, since Stella will now default
to using accurate positioning, and not use ´tweaks´.

* Joystick code now allows all 4 directions; ´Bumper Bash´ now works
correctly.

* Improved Keypad emulation; ´Alpha Beam with Ernie´, ´Oscars Trash Race´
and ´Magicard´ now work correctly.

* Reworked GUI code, so that all dialog boxes are automatically centered.

* Added ´rominfo´ commandline argument, which prints some detailed info for
a ROM.

* For the OSX port; fixed crashes in OpenGL mode.

* For the GP2X port; some improvements to the sound code.

* For the GP2X port; added vertical centering of the TIA image (when possible).
