Made games page CSS more generic.
Changed the name of the “Game” layout to be more generic.
Added a basic projects page with an entry for the terrainarizer project.
Wording changes
Added nav link to the projects page
Changed the way that the top nav bar displays on small-screen devices.

Now displays as 2 rows, with site name on top and links on the bottom, when the screen is too small to keep everything on the same line.
Added small version of the terrainarizer screenshot.
