Update
Huge Changes

All Images have been shrunk (still same quality) with PNG Gauntlet.
Through my own tets I have found that it works 1 to 2% better than
Smush.It.

- Added better Handlebars recognition
- Added better HeadJS recognition
(https://github.com/ElbertF/Wappalyzer/pull/520#issuecomment-40873684)
- Added Spin.js, Font Awesone, Jekyll, Ionicons, and math.js
