This iteration:
Places the resulting bundle folder off the top of the tree, rather than as a subdirectory of src.
Leaves the Applescript files out for now.
Builds the Info.plist (for now) via hard-coded values in the Makefile.
Builds the bundle launch script on the fly at make-time.
I think this revision may be working, at lease on my test machine.
There are more improvements to be done.
