Added Polymer, Ink, Zurb, Bootstrap, GWT, Vaadin

Added
* Polymer
* Ink
* Zurb
* Bootstrap
* Vaadin
* GWT

Added back GWT after reworking not to trigger security warnings. Now only attempts to access `iframes` that are very likely to be GWT iframes, unlike before when I had it run through all iframes indiscriminately. 

Fixes #20
