Change verbose_name of founder property in Group model from "Created by" to "Founded by". Add GROUP_TYPE_SHORT and GROUP_TYPE_PLURAL for all models that inherit from Group and use that values in templates and contexts. Assume that group_type, group_type_short and group_type_plural are defined in context and remove not needed ifs in templates. Rename "Linkname" to "Link name" in list/group_heading.html template.
