Small updates

-Changed the small button at the top, and made it the login button.
-Changed the tiles and background colors because I got tired of the
white, and added hover changes for the tiles.
-Changed the search bar to have 'search' pre-rendered in the bar, and
changed the background bar. It still does nothing sadly.
-Add calender.jade to routes but still has no js file so
localhost:3000/calender does nothing but reroute back to the index page.
In process of updating front-end
adding changes
Stable before restucturing jade files
Major upgrade to the interface

  -Separated layout.jade so that it renders the top
  navigation bar and a "content_block" to be filled in
  by specific .jade files.
  -Provided new css classes and ids in attempt to simplify
  building of later pages
  -Changed the way objects were created and passed to pages
  to be rendered in index.js. (not sure if new way is better
  or worse, I think it looks better but I would like someone's
  review)
