Replace the dialog-based TableStructureEditorDialog with a tab-based
TableStructureEditor, making it consistent with query editors, data
viewers, and object browsers. Users can now switch between editing
table structure and running queries freely.
Object browser now defaults to showing tables when tables exist.
Table/view context menus match sidebar tree with structure editing,
export, import, diagram, data compare, truncate, empty, duplicate,
and copy name support.
