cpp: Add support for trust signatures to sign key edit interactor

* lang/cpp/src/gpgsignkeyeditinteractor.h,
lang/cpp/src/gpgsignkeyeditinteractor.cpp
(GpgSignKeyEditInteractor::setTrustSignatureTrust): New.
(GpgSignKeyEditInteractor::setTrustSignatureDepth): New.
(GpgSignKeyEditInteractor::setTrustSignatureScope): New.
* lang/cpp/src/gpgsignkeyeditinteractor.cpp
(GpgSignKeyEditInteractor::Private::Private): Initialize new member.
(makeTable): Add new transition. Fix typos in existing transitions.
(GpgSignKeyEditInteractor::action): Handle SET_TRUST_VALUE,
SET_TRUST_DEPTH, and SET_TRUST_REGEXP.
