Added GP2X port, thanks to Alex Zaballa. This is the first commit,

so I may have broken something.

Improved 'joystick is mouse' code in the GUI.  Also account for devices
where the D-pad sends button events instead of the normal axis events.

Treat joystick events as other types of controllers based on the
virtual port entry in stella.pro.  This means that mappings for a
joystick will emulate other devices when necessary, and should
help on 'small' devices with few inputs.

Added 'sp' developer commandline argument, which sets the
"Console.SwapPorts" property and swaps the arrangement of the
virtual ports.  Useful for games like "Raiders of the Lost Ark",
where the joysticks are normally swapped.  Updated stella.pro
for Raiders to use this property.

Moved ugly #ifdef code for screen dimensions out of FrameBuffer and
directly into the respective OSystemXXX classes.

Added 'freq', 'tiafreq' and 'clipvol' commandline arguments, which
affect the sound subsystem.  Note that none of these add new
functionality; they merely expose what were previously constants
in the code:
 - freq: sets sound sample output frequency
 - tiafreq: sets sound sample generation frequency
 - clipvol: clips volume to eliminate huge cracks when pausing sound
