#38 Fix for Gimp.app not showing as Universal in Finder

[Lo, Kwong Chi]

Hi!
Here is a Universal binary build of ScriptExec.
Copying it as Gimp.app/Contents/MacOS/Gimp let Gimp.app
show up as Universial in Finder, and improve the speed
of the bundle too.

Another note,
Gimp.app/Contents/Resources/bin/cache-fonts is still a
PowerPC only binary.

Thanks for supplying us the great Gimp.app!
