DOC: Add an XSD for PSYEXP XML format

The XSD is only basic and does not care about most of the special cases.
For example there is no check for LoopInitiator and LoopTerminator pairs
and if Routines referenced in Flow are actually definied. But structures
and most of the other restrictions (unique names, enumerated valType and
updates, available Components) should be checked.

FB 504, SetDeviceGammaRamp fails x64

On x64 SetDeviceGammaRamp fails about half the time due to an improper
sign extension bug in pyglet.  This fix should work 32/64 and will also
continue to work once pyglet fixes the bug.
Monitor selection box too narrow.

Switch from 200 wide to 500 wide.
Revert "Monitor selection box too narrow."

This reverts commit d8db1712077b392b125ee5e1c256eaf03216a42f.
