Fully operational gulp and metalsmith based site builder

This also contains a few other config files with more to come.

I should really make a yeoman script out of this...
Landing page with same very basic alignment
publish task for github pages
added a CNAME for github pages custom domain support
Temporarily remove cache buster on main.css

This will need to be added back once the asset build process has been
reworked to also include a rev replace option.
Merge branch 'feature/landing-page' into develop
bump
Merge branch 'release/0.1.0'
