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.
Interesting. I'm sure we'll figure this one out together ;) Jquery should normally get concatenated into `application.js` making this line unnecessary, but for testing it's helpful. We'll just make sure it doesn't stay in one we get the js compiling correctly. :)
