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.
It's odd, because the page is definitely seeing and pointing towards the Foundation JS. What I'm seeing is a `foundation.js` file in the main assets folder (which is empty), and then also a `foundation` folder, which has all of the 5.3.0 code. I wonder if this is a scope thing on the JS end, where that code isn't getting properly initialized?
