Subject: [PATCH 2/2] gitweb: support to globally enable/disable a  
snapshot format

I added a 'disabled' variable to to the $known_snapshot_formats keys so
that a Gitweb administrator can globally enable or disable a specific
format for snapshots.

All formats are enabled by default because project specific overriding
is disabled by default.
