After much thought, tests and discussions with Aryeom, we decided adding back an active item concept additionally to the selected items ones is a bad idea as it makes only usage unecessarily complex. We will just have selected layers. Some kind of operations will work when more than one item (layers, channels, vectors) are selected while others will require exacty one item. In particular, let's replace instances of gimp_image_(s|g)et_active_*() by corresponding gimp_image_(s|g)et_selected_*(). Also replace single item in various undo classes by GList of items. Also "active-*-changed" GimpImage signals are no more, fully replaced by "selected-*s-changed". This is still work-in-progress.
