add circuit to verify signatures (SignatureVerifyGadget) (#167)

Browse source 
* implement circuit to verify signature (proof-based signature), ie. a 1-level recursion verification

* as agreed in the call, rename Gate -> Gadget when it's not a 'gate'

* make SignatureVerifyGadget conditional on the selector input

* small naming polish

* sigverifygadget: add s computation in-circuit, connect pk,msg,s to internalproof's public_inputs

* optimize signature verify
