IIgs: Turn color back on when launching other programs

[inexorabletash]

The initialization code pokes a IIgs softswitch (NEWVIDEO) to force monochrome mode during DeskTop launch. This state is not reset when launching other programs, thus preventing them from displaying color.

This should be in the reset_and_invoke routine (circa main $5AEE) where all the other softswitches are set.
