* 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.

Objectives:
* Got rid of mw prefixing in tools, inspectors and dialogs
* Simplify tool classes so they can be generically used as items in bars, lists and menus
* Add support for a catch-all toolbar group
* Simplify tool registration, leaning on tool classes' static name property
* Move default commands to command registry
* Move default triggers to trigger registry
* Get language tool working in standalone
