Turbogears2 migration: remove some references to Pylons in comments In order to minimize the diff of the actual Turbogears2 migration, this commit already removes certain unnecessary references to Pylons from the Kallithea source base. Places where the reference to Pylons is important are still kept for now, as well as references in kallithea/config where many changes are made for Turbogears2 anyway.
