Start of refactor 07-21-2014

Some very major changes as this is the first PR of the refactor:

-Deleted lots and lots of code that is either dead or of no use to us anymore
-Built new plugin for custom NGDS UI w/ some basic routes (we don't have anything to link to yet really)
-Built templates w/ responsive CSS for account header, navigation header and footer.  I mostly just copied data.gov's color scheme and basic layout.  We might want to change the color scheme to make NGDS look less like data.gov.
