Email Validation, Re-Org, & Clean Up

This is a major commit which was used to iron out a few outstanding
bugs as well as to finally implement an email verification system into
the user self-registration form. I also re-arranged lots of files and
updated their references accordingly. A CDN was also created for a few
things as well as a new vhost specifically for tracking pixels. There
are still a few known bugs left to fix but for the most part the
majority of the application is working like a champ. Thanks SendGrid.
