Add a simple dmg script to the mac build dir to build a dmg out of the app.
Add a target to build a dmg out of the app.
Add a target to all that will build everything and the dmg (since we don't include the dmg in all since developers really don't need to wait for that).

Maybe don't set -x 'til you call pkg-dmg.  We don't really care to display
what's being assinged, do we?  Same goes for -e because the sets can't really
fail.
