Un-suck front page! Login support!

* master/icons/Makefile:
* master/icons/home.svg:
* master/master/templates/basic.html
  - Replace login.svg with an edited version of logout.svg
  - Add a new icon (home.svg), and it's logged-out version: none.png
  - Use logout, login, home icons
  - Modify header to accomodate login/logout/home icons

* master/master/templates/frontpage.html:
* master/master/media/css/frontpage.css:
  - Fix the frontpage to not suck while displaying the "pieces" (the
    4 large images)

* master/master/templates/registration/login.html:
* master/master/urls.py:
* master/master/views.py:
  - Implement login!
  - Also, implement awesome login/logout image behaviour ;p
    * Using RequestContext()
    * none.png/home.png are implemented in the same way
