[sugar] sugar-jhbuild: moved squeak repository

[Bert Freudenberg]

Hi folks,

I moved the Squeak VM build to an "olpc" branch on squeakvm.org. You  
need to pull the new module definition and remove the old sources:

	cd sugar-jhbuild
	git pull
	rm -rf source/squeak
	./sugar-jhbuild buildone squeak

The switch to this branch will allow faster turn-around for us.  
Currently this branch has the big cursor support and improved camera  
plugin which is not in the mainline VM, yet.
