Rémi Verschelde 01afc442c7 Signals: Port connect calls to use callable_mp 
Remove now unnecessary bindings of signal callbacks in the public API.
There might be some false positives that need rebinding if they were

No regular expressions were harmed in the making of this commit.
(Nah, just kidding.)
