Merge branch '0.9.x' of gitorious.org:statusnet/mainline into 0.9.x
* '0.9.x' of gitorious.org:statusnet/mainline: Localisation updates for !StatusNet from !translatewiki.net Use the browser's geolocation API to set the location on the notice form Add geometa library, and include it. Add location form elements to the noticeform, and save their values on submission Use the $user object nickname, as login name doesnt have to == nickname anymore with plugins such as ldap/etc Revert "Re added NICKNAME_FMT constant to router.php."
