OS X Time Travel UI

Change-Id: Iceb8bdba9aa8dabb9f86caffe88b0ccdfa3f4deb
server/ui: set Content-Type when serving .svg.

Fixes warning 'Resource interpreted as Image but transferred with MIME
type text/xml:' on Chrome, and more importantly returns the previously
missing icons to my camlistore instances.  Everyone else must be
hitting cache, or something is weird with my setup.  I see missing
icons on Safari / Chome on Mac, and Firefox / Chrome on Linux.
