Added sidebar with 5 most recent books.
We can change the side bar as necessary and include what ever we desire.
During this I found a few bugs:

	* we create a new user file on line 81 and I don't think we need to
	* We should create a seprate function for obtaining a users profile
	* view.html's {{.body}} needs to be limited to a specific number of pixels
	* I should look into making css compatible with devices of different screen sizes
