Revisited changelog storage & display
Fixed #656

INNER JOIN caused deleted rows to no longer appear in the changelog
query, because the corresponding content row no longer exists.
Store the title at the time of changelogging, along with the actual log
Tweaked functional tests

Updated database fixture, nicer error reporting for user login.
Fixed: changelog crashed when publishing / depublishing

This was due to the way the changelog title was determined; the
updateSingle function did not pass a title along. The fix is to check if
a non-empty title could be derived successfully, and reload the entire
object from the database when there is no title.
Only show changed fields in changelog
Differentiate between status changes and regular updates in changelog
Serve a 404 when trying to access nonexistant content items
Fixed: changelog crashed when viewing entries for deleted pages
Setting max-width for CKEditor to 1500px.
