Update **some** dependencies

* Update font-awesome
* Update bootstrap-markdown **NOTE** #366 is included in this so backing out that patch
* Update github package ... check okay with import and login
* **Remove** highlight package as it seems Ace handles this natively and no references *(require)* found
* Update request package ... check okay with import
* Update underscore lib... **not fully tested**
* Update passport package ... only tested with GH login

* Fix link for select2-bootstrap.css on GH
* Reference newest Ace build

This leaves:
* mongoose *(this will need major testing to make sure we don't break acccess when updated)*
* aws-sdk *(this will need major testing to make sure we don't break acccess when updated)*
* bootstrap *(still stalled as per Zren)*
Update Ace to 2014 10 09 release

* Manual addition of GM API again ... fix a spacing issue from last update
* Recursively **remove** snippets subfolder for production
* Match GH download zip dates during extraction
