Add knobs to enable/disable files/lines changed in log view

These columns can cause lots of IO on the server, so add settings to
explicitly enable them. Also, add per repo settings to optionally disable
the columns if sitewide enabled.

While at it, do not allow repo.snapshot to enable snapshots if the global
setting is disabled.
