Fix web status page reloading
Fix web status page reloading

The javascript_revision was getting set to the revision that the master was
running, rather than the most recently checked out revision as it should have
been.  As a result, if the master gets synced without a restart, the web status
pages will refresh over and over instead of just once.

Requires a master restart.
