remove unnecessary architecture code from Mac OS X Universal binaries

ditto --arch i386 doubleTwist.app doubleTwist_i386.app
ditto can be used to "thinnify" Mach-O Universal binaries to separate unncessary code from your machine. For example, doubleTwist.app shaved off around 10 MB while Google Earth went from 112 MB to 62 MB after extracting only the i386 code from them.
