Updates to latest MIT branding

Relevant ticket(s):

* https://mitlibraries.atlassian.net/browse/PW-68

Document any side effects to this change:

* a couple files now loading from the CDN were deleted from the public
  directory
* local favicon was updated (it's a fallback and likely only used by
  IE at this point)
