Added CSP on both angular and hapi

Added CSP, Content Security Policy to both angular and hapi. This will
protect the site against XSS attacks for the most part. The only
weakness is that styleSrc is left at 'unsafe-inline' to allow jQuery and
some other JS that we're including to actually function.
Updated CSS for main page and board page

Optimized some of the CSS on the main page and board page. Also removed
useless code found throughout those pages. Also removed the login page
as it is not being used.
Streamlined the CSS across all the pages

Removed unused CSS, renamed all classes to be more semantic, and
streamlined all css across all pages.
Added missing dependencies for scooter and blankie
