Final pass through code to identify dependent open source licenses

[RobertStewart]

Review all the code and third party libraries, then document all their licenses in the license file. Then, add an open source license for the overall project.

jQuery and jHash are MIT licensed. Michael, can you please select a license for Treena? I'm planning to use the MIT license for the entire app, so that would be a compatible choice.

The license for my only previous open-source effort is herehttps://github.com/Malvolio/ie.xhr, but yes, MIT is fine with me.
