Subject: * Add wrappergroup config option, which can be used to cause wrappers
   to be created owned by some group other than the default. Useful   then
 there's a shared repository with access controlled by a group,   to let
 ikiwiki run setgid to that group. * ikiwiki-mass-rebuild: Run build with the
 user in all their groups.
