Title: Bugs in RGraph's morph (directed graph), and a feature (positioning the arrow in middle of edge)

I'd appreciate some help here to prettify the code a bit (though it's not long). All bugs were causes since the graph isn't really directional (only the $direction property indicates), and this info wasn't used in some traversals.
I can send you more details when and how it solves the bugs, and especially more scenarios were the bugs occur.
Please excuse the extra commits (due to CRLFs), the diff is only a few liner.

Cheers,
Oren Rubin
