OLEFA 18.6: Fit for future

1. CMS:
   • The you are here path now indicates the name and ID of the current wiki project again.
   • When using the contact users functions, all relative links and sources are automatically converted in absolute links, so that they work from within the mail.
2. OLEFABase:
   • The default type is now also respected inside custom add forms.
   • When copying or moving a record to another database, the image gallery is also handled accordingly.
3. Timeline:
   • Fixes a problem where embedded Youtube videos were no longer displayed correctly.
   • Fixes a problem where year-based timelines still asked for a precise date.
4. Pinboard:
   • The abuse-report now also contains the e-mail address of the person that reported the problem.
   • When editing an existing entry and uploading new files, the interface no longer freezes.
5. Various bugfixes and performance improvements, including adjustments for new server OS.
