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.
Totally my bad—this is good! At first I thought `jquery-ujs` was a typo :stuck_out_tongue_winking_eye:. Did you remove it because we weren't using it or did you perhaps think the same?
