hgweb: break templater -> templater circular reference The problem were some functions passed in the "defaults" argument during the templater creation which use "self.t" directly. This creates the cycle: hgweb object -> templater object -> defaults dict -> footer function -> hgweb object Instead of completely avoding the cycle, we break it after using the templater.
