Started converting to MVC (Model View Controller) layout.
Added Room has_many Posts relationship.
Added cascade to Room->Post backlinks. Needs to be tested.
Added post controller to handle REST API.
GET posts/ and GET posts/<id> should work now.
Added ui and changed longitude and latitude to floats.
Removed all references to Post.title.
GET /posts/, GET /posts/<id>, and POST /posts/ work. Others not tested.
Merge branch 'testing'

Conflicts:
	data.py
	geopost.py
	post.py
	ui/ui.html
