* Move and rename generic parts of ve.ui to OO.ui * We now have a UI test suite because ve.Element (outside ve.ui) is now part of oojs-ui, so it needs a test suite. * Added to the MW test run (just like we do for unicodejs). * Updated csslint config (also added ve-mw and syntaxhighlight which were missing). oojs-ui still depends on the TriggerRegistry in VE, this is addressed in a follow-up commit.
