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)
This would be notated in Django like this:

{% url 'projects' %}

Assuming that the view is named in urls.py
