* src/ui/group/TabbedGroupUi.js (doShowField, doHideField):
Return from method after setting deferred operation. This previously
did not fail because jQuery didn't care if operations are not
performed on field matches.
* src/ui/GroupUi.js (getFieldElements): New method
(showField, hideField): Use GroupUi#getFieldElements
* src/ui/group/TabbedGroupUi (showField, hideField):
Use GroupUi#getFieldElements
The `AccordionGroupUi` was not liberated, because it is my intent to
eliminate it---I did not agree with its needless addition to begin with. If
we do end up keeping it, then it will be liberated as well.
