- Updated Windows build doc, very slight revision.  Changed 37 targets to 38.
- Added plugins/imagehl to list of modules built (both	Windows and Linux).
    Not	really sure what this does, but it's the only module (as defined by
    stuff in plugins/ or contrib/) that exists and isn't currently part of the
    build.
- The code to disable desktop composition in Windows has been moved from start
    of main() to an option in Preferences.  The	pref reads as follows:
    "NVIDIA/Aero bug - disable Windows composition".  It is enabled by default.
- Color themes controlled by "Misc" -> "Colors" -> "Themes" options are now
    saved as soon as you select them.  The color theme is no longer clobbered
    when opening Preferences.
- The ATI broken driver (bug #802) pref has been reworded since it applies to
    Intel cards as well.  Before:
    "ATI cards with broken drivers - bug #802".  After:
    "ATI and Intel cards w/ buggy drivers (disappearing polygons)".
