Fix Site.find_for_request to not assume that request.META will include an HTTP_HOST - the django test client doesn't, by default
Gracefully skip elasticsearch backend tests when elasticutils/pyelasticsearch isn't installed
Stop wagtailadmin/pages/list.html from breaking when output includes the root node and show_parent=True - fixes #78
Adding skips where we don't yet have real tests but want to keep the files around and still have an accurate test count in the meantime. Addresses #51.
Fix some minor LESS syntax errors (handled by lessc, but important if we switch to a less permissive LESS compiler)
Finished string extraction for i18n

Also a minor bug in preview for moderator has been fixed: The
_moderator_userbar.html template contained the date in the "d M Y" format,
which means that a string with the name of the month would be written.
When the locale was 'el' this would contain a string with greek characters
something that would leat to a 500-error when the wagtailuserbar would be
called. This could be solved either by changign the date foramt to Y-m-d
(iso format, which is what i chose) or by adding a u before the '' in line
11 and 15 of wagtailuserbar.py.
Previous commit had again "M" in the date-fixed it
