Fix SubscriberTest->testItHasGroupFilter() making only one of four assertions due to lack of data.
Fix a small issue with Import. Unexpected values for the status field were converted to 'unconfirmed' rather than 'subscribed' due to non-strict comparison in in_array(). This hindered 'bounced' status import as well.
- newsletters listing now uses hash history
- newsletters are sorted by Subject (a->z)

- added explicit error messages when an auto newsletter isn't fully configured
- added missing strings for "selectAll" in Segments listing

- set default sender based on settings when creating new newsletter
- fixed erroneous UTC offset when displaying dates (PHP takes care of it)
- fixed duplicate entry in Robofile for editor styles
