GUI: Add ListWidget commands: single click and edit start

Browse Source 
These commands allow greater control over editable ListWidgets, although
the save dialog's list is currently the only one.

kListItemSingleClickedCmd allows clients to respond to selection changes
based on the method used (mouse vs keyboard) and allows responding to
clicking on an already selected item. In the next commit, this will fix
multiple save issues.

kListItemEditModeStartedCmd allows clients to initialize edit mode
consistently. The save dialog has been doing custom initialization after
calling startEditMode, but this is incorrect because ListWidget calls
startEditMode in response to Enter, so the initialization is skipped.
