Remove the old products page Update links in Tabzilla
I looked at the logs and dev was being deployed more often than it should have based on changes in master. This is due to the request to www-dev.m.o/media/revision.txt sometimes returning a 500 page. This is seen by the script as different from the hash on github, and thus it deploys. The problem is that this error is most likely just the previous deploy finishing up since deploys now take longer than before. This change both reduces the frequency of autodeploys to every 20 min and checks the local revision.txt for what is currently deployed. We might consider moving to a python-based autodeploy script in future for more flexibility in checking things on the dev server and github.
Also fix dev chief autodeploy script.
