Ironed out the kinks in editing apis for GtkCellArea
- Added gtk_cell_area_aligned_cell_area() to get the aligned internal area use by a cell (for focus painting and for event areas). - Provide the event area in "editing-started" signal - Fire "remove-editable" when editing is canceled by the user, an implementing layouting widget need only catch "editing-started" and "remove-editable" now. - CellAreaScaffold/testcellarea now edit textrenderers.
