modify Selection API to provide (default-valued) "with_signal" argument to all ::clear_*() methods
This allows the clear methods to be used before calling ::add(), to avoid the
emission of a signal saying "there are no <foo> selected right now".
There should be no side-effects from this commit.
Note that correct use of this new API is complex, and requires avoiding the use
of wrapper methods like clear_objects().
