Initial work for GlyphString editing and extensible data path

[syntelos]

Sven, I think the commit logs tell the story. I'm going to take a break and get back to this in a couple days to wrap up the remainder of the StringBuilder API to append to the CharSequence API -- as documented in GlyphString.

(Not sure if we discussed the github account name subject, thought about it and would prefer to change it -- i've got an organization going that's simple and reflects lessons learned from [email protected]).

All comments most welcome, John

Not sure why my diffs are so ugly.. in one case i dropped mangled CR characters which could do that.. (sorry)

The only real change aside from a basic merge is getPaths(String) to getPaths(CharSequence) -- (mod to Rami's change from getOutline in support of a new meaning for getOutline).
