Uncovered and fixed a bug where $session->user instead of $self was used in canUseAdminMode
Added an explicit test in Config.pm to make sure that array refs can be passed to ->set.
- fix: cacheTimeout not respected as Visitor (Eric Kennedy).
- fix: Email address with just one character in the user part not accepted
- fix: Image (file) added to page shows before committing changes
- fix: Typo in fileImport.pl at line 265 (zxp)
