Subject: ScummVM/PS2 bugs fixed by this commit:

 - general file write corruption (eg. ScummVM.ini, etc.)

 - COMI specific save crash / corruption
   (added option in engines/scumm/saveload.cpp to disable
    thumbnails on PS2, as emergency fallback in case the
    fix should prove to be insufficient)

 - implemented _screenChange logic
   (fixes grabOverlay & COMI popup menu)

 - fixed higher pitch (chipmunk fx)

 - made NET IRXs optional to allow it to work on fat PS2 without net+hd

 - fixed cursor restore on RTL

 - added "." as R2 to skip single lines of dialog

 - added write cache
