Restore /c2/ URL handling

The ChangeScreen2 experiment is still fairly new.  A number of links
exist outside of Gerrit using /#/c2/...  to view a change and enable
new UI.  Continue to accept /c2/ as a temporary override in the
current tab.

Leave a hack inside of Dispatcher for now.  Once ChangeScreen2 becomes
the default most of the hack can go away, but it may be necessary to
continue to accept /#/c2/ as an alias for /#/c/ to prevent breaking
some URLs.
