Projects page created

Added a new Projects page to the app.
- Index.html - added a link to the new Projects page
- created a new static projects.html 
- created a view for Projects page using the render function instead of render_to_response (as Anamarija used for index.html) (views.py)
- added a new url pattern for Projects (urls.py)
The view should have a name, so we can reference the name of it instead of path, which could change (it should not, but still). Example:

url(r'^archive/(\d{4})/$', archive, name="full-archive"),
