A quick add guide page.

Added a quick add guide page that asks for the name of the guide and the author id. This is to make population of my own database easier, but I know a bare minimum of RoR, so might not be ideal and needs expanding.
Might be faster to source this from one of [Google's CDNs](https://developers.google.com/speed/libraries/)?
I'm not Ruby experienced enough to know, but is this the best way for us to include page-specific JS scripts? @rickcarlino?
