Created projects page

Started making the layout for the projects page. It’s just a static
page for now and the code still needs to be cleaned up quite a bit, but
should give a nice introduction to how this page can look. Next step is
to make a view where users can add their project info, and have it
dynamically update the list of projects. Let me know what you all think
of it so far.

Tried to commit to projects branch, /projects/index.html.erb will not
upload for some reason.
