Smart social

@gholtslander 

Biggest changes:
- Updates to nav bar
- Contact us page
- Social integration on each page

Smaller changes:
- Updated the fullpage files to be _min versions. If we like this I think we can just delete the full ones from the app and only serve the minified or compressed ones. As long as they're still legible that's probably good to do (though it won't really do anything besides save us some space on the server allocations)
- Added the Open Graph tags to each page. I need to update them to be helpful in some cases, though
- Removed all (or most) of the unused images from the repository. Should make cloning this repo easier if we ever need to do that again.
