TIDOC-1138 Tooling updates for 360

A couple of notes:

- With these changes, we only really need two JSDuck config files--one for cloud and one for everything else. The title is passed in to deploy.sh as a command-line argument (-t "title"). Note that the title takes a particular format -- "Titanium 3.X - Appcelerator Docs" for example. JSDuck does magic with it and uses the two parts in different places.

- The docsite paths for the pulldown menu are now relative, which means you can serve the docs out of (say) localhost/~username/titanium/latest and the links will work correctly.
