[PATCH] gitweb: Support hiding of chosen repositories from project list

[Petr Baudis <pasky@suse.cz>]

This makes it possible to hide certain repository from project list
(while still keeping it accessible, so it's not just an inverse of
 export-ok). By default the file that needs to be created in the
repository is '.hide'.
