CSS and JQuery on show page and show stylesheet

Additionally -- a minor change to the controller: I added '.titleize' to the search params so they will match our venue name strings, all of which are capitalized. Perhaps we will change much of the search logic altogether, but this is a helpful patch for now. 

I also deleted the tags controller and the details controller as we are not using them, but perhaps best to ignore this change so as to avoid frustrating/confusing Lior.

Finally, for some goddamn reason, despite adding database.yml to my .gitignore and, presumably, removing it from my git cached, it is still showing up. please ignore its changes.
