#5 Include MathJax typesetting

[Nathan Carter]

Currently GE has limited math notation support. If we upgraded the web view widgets to full webkit widgets, and imported MathJax (as is done in the Lurch project), we could allow users to type in arbitrary TeX for things like element representations.
Getting such representations into the OpenGL views, however, will require using something like qtmathjax to render them as a .png w/transparency, maybe to be used as a quad texture?
