Re-enabled selenium tests (currently some are failing because of a JS error)
New (failing) test. Now the remaining one-third of the job: fixing the bug.
XML file bound to the new test in the last commit (aaarg, I already pushed and can't amend the commit)
Fix the test db xml
Merge branch 'github-main' into selenium-testing
Selenium tests still disabled. p.a.testing exportimport test works fine
Fix schemaextender import/export: it should now behave properly also with unicode chars.
Merge pull request #297 from plomino/selenium-testing

thank you @silviot :)
