Cleaning up the template


#1: Moved copyTemp task to 'build' because it's much clearer
#2: install for packaging into build not build/www (again it's clearer)
#3: removing example code in web/

#3 is the only controversial change, which I'm suggesting because I think it makes more sense to do this than have code in web that makes it less clear which is template vs which is app, but I'm open to debate.
