Simplify theme by backtracking to original.

Theme I was using didn't make a lot of use of layouts but instead
included snippets to build the various pages.
Basic layout setup with Bootstrap
More work on new theme.
Some playing around with page header.
Clean up remnants of old theme.

Remove old files that came with the old theme I was using. Also split
out the style overrides to it's own CSS file.

The current setup is very basic and using CDN for bootstrap and
font-awesome.
