Record and display update logs

At the moment it's a bit difficult to get update logs out of the
environment in which the update script is being run. In order to make
the logs more accessible, create a LayerUpdate model to record the
output of update_layer.py separately for each layerbranch and tie the
created LayerUpdates together with a single Update model per session.

We provide two ways to look at this - a Tools->Updates page for
logged-in users, and there's also an "Updates" tab on each layer that is
accessible to anyone; which one is useful depends on whether you are
looking at the index as a whole or an individual layer.

Update records older than 30 days are deleted automatically by default.
