Merge pull request #131 from msecret/ehnc-new_designs_project

Start on new designs of project page
New design of landing page

Added grid component for basic grid work. Starting to get rid of
css showcase class. Fixed neat by moving grid-settings into own file
and including it before neat.

TODO:
- Make grid component filename underscored.
Removed the grid.css file

It was a mistake that I created it without the underscore to mark it
as not compilable into own file.
