Hide Gerrit permissions projects by default

[GoogleCodeExporter]

[Discussion condensed from another bug tracker.]

The permission container projects like All-Projects, or Kernel-Projects on 
android should be hidden by default from the host index. These aren't really 
interesting for someone looking at source code.

There are times that an admin wants to browse these, so we should still make 
them available, but maybe collapse them under an expand out toggle, or move 
them to a second page with a link shown at the bottom of the main project 
listing.

Possibilities:
-Hide repos where HEAD points to refs/meta/config
-Hide repos that contain only refs/meta/config
-Hide repos that contain no branches or tags
(All of these are straightforwardly implemented in DefaultAccess or other 
GitilesAccess implementation.)
