Not compatible with OG7.x-2.x

Would be good to put on the module page for this that it should only be used with OG7.x-1.x. So many of the CM modules seem to require latest dev versions that I figured the same would probably be the case with OG, but when using OG7.x-2.x cm_project throws a php fatal error when you go to the show tab on on a project. The fatal error is undefined function for og_get_group() line 178 of cm_project.module -- this function is not in og.module OG7.x-2.x version (at least not the current dev version).
