[feladat @ 182] Merged r125:181 of branches/rewrite-user-management into trunk. This incorporates the [wiki:ProposalUserPermissionManagement a new user and permission management system] and closes ticket:22. Be aware, this database structure has changed, this version is incompatible with previous versions.

[feladat @ 159] Bugfix for ticket:16: A minor glitch in the query caused partially owned records not to be shown.

[feladat @ 158] Bugfix for ticket:18: Minor modification in the CSS to make sure no data is displayed on top of other data. Also a little modification to make sure the sub-owners (if there are any) are displayed above the record form, instead of next to it.

[feladat @ 156] Made a lot of small changes to allow PHP to run with error_reporting E_ALL without giving notices. Most functions have been checked but some situations might give a notice.
