WD: bind all avaiable incoming slots to the destination slot

1) Open WD.
2) Add Read Sequence (RS).
3) Add ORF Finder (OF).
4) Connect RS with OF.
5) Add Write Sequence (WS).
6) Connect OF with WS.
=> Input "Annotations" slot of WS is empty. It is because of the current implementation of bindings: autobinding works only in the case of single incoming slot of the needed type.

Replace this behavior with the next: bind all suitable incoming slots.
