Merge branch 'testing' of gitorious.org:statusnet/mainline into testing

* 'testing' of gitorious.org:statusnet/mainline:
  Merge StatusNet core localization updates from 0.9.x branch
  Fix update_po_templates.php to support the plural and context variants of _m() in plugins
  Drop HTMLPurifier; we don't need its extra capabilities and we're already using htmLawed which is lighter-weight.
  OStatus: handle update-profile Salmon pings
  Revert "Updated jQuery Form Plugin from v2.17 to v2.36"
  OStatus: disable HTMLPurify cache unless we've configured a writable path for it.
