The old API to select stuff and its signals was doing unexpected stuff and was very confusing. Change things to be "normal": The selection API is now set_selected() and get_selected(), with no internal data exposed, and set_selected() emitting the expected signal. The signals are now "selection-changed" and "item-activated". "selection-changed" is always emitted in response to changing the selection, be it via the API, or by changes in the model (the internal callbacks in from e.g. GimpContext or GimpImage simply call set_selected() and don't do any unxpected magic).
