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

Create getter for extensionsName which is overriden by
MWAlienExtensionNode.
Also removed angle brackets around Alien title as the inspector
already has an angle bracket icon, and a '<' close button.
