Modified the ExternalView so that relative links work correctly for
URL's that end with just a directory name instead of a file name or '/'

Add -moz- and -webkit- attributes to default theme CSS for better
browser cross-compatibility.
ExternalView.js now loads relative link and image paths by manipulating
the url upon clicking and changing img src attributes upon rendering.
Modified the scroll to anchor function in ExternalView so that it will
also work for Sphinx-created documentation, which does not use the name
attribute of anchor tags. It will now search by id if no element by name
is found.

Also created the styling for the docs for each theme in the #external
view.
Changed font weight for the KNB theme docs.
Changed the 'edit map' part of the advanced search design mockup.
Added some styling to each theme for the emlparser pages when viewed in
the external view
use "default" theme in the checked-in repo version.
