CORE-4073: Ongoing changes and corrections for analysis launch
* Tooltips are now dynamically added to most controls in edit mode.
* Hierarchical List control now has default selections coordinated
between center and property editor. Cascading actions still need to be
addressed.
* Changed the way the GWT editor hierarchy is bound. In center, binding
only goes as far as ArgumentEditor. All sub controls, which are
dynamically created based on ArgumentType, are manually updated, set,
and flushed. This reduced many conflicting value sets and bulky
coordination code when in editing mode. Phew!
* App launch should now be mostly working.
