Remove examples directory; these now live in gf-contrib

All changes have been reflected in the gf-contrib repository:
https://github.com/GrammaticalFramework/gf-contrib

Now, for WebSetup to build the example grammars, one must have gf-contrib
cloned in the same top-level directory as GF. When this isn't the case,
WebSetup displays a notice without failing.
