Theme the individual course about pages

Use the theme's own Google Analytics template (should probably
update to just use parameters once the default GA template is kept
up-to-date). Don't link to the university profile page when a theme
is enabled, as that's an edX-specific feature. Adjust social links
for Stanford, but leave them alone for everyone else (this is just
a hack for the 6/11/13 launch).
