Convert Assets

Assets have been converted as follows:
- Change to gulp instead of grunt for build system
- Remove bower and manage with npm instead
- Change to postcss instead of sass
- Change to Pure.css instead of foundation (lighter weight)
- Update Icon Font
- Initial rework of site styling (layout will be committed with updated
  style later)
- Removed extra js which was not really needed
- Built js and css will be in the assets/dist directory

This really should have been probably 20 commits with a rebase or
something...
