Use selection->regions instead of Editor::get_regions_from_selection()

Remove Editor::get_regions_from_selection(), and use selection->regions
directly in the few places it was called.
Ignore track selection if there are any selected regions.

Make Editor::get_regions_from_selection_and_edit_point() only consider the
selected tracks when finding regions to operate on if there are no regions
selected, and never if the edit point is 'mouse'.
Don't include unselected regions in edit grouped region operations.

Make Editor::get_regions_from_selection_and_entered() only return regions
that are actually selected or entered, not their unselected equivalents.

Update region_ops.txt to match current behaviour, and fix a couple of comments.

Update region_ops.txt to better describe the current behaviour of

comments that still referred to the no-longer-existing 'edit' property of
route groups.
