[gocrypto]: add Jenkins for gocrypto

problem: no Jenkins job for gocrypto
solution: add Jenkins job for gocrypto

[nis]: prohibit multisig transactions with same inner transaction but…

… different signers

 problem: when a new multisig transaction is received, the hash of its inner transaction is not checked
          against hashes in the HashTransactionsCache before being added to the UnconfirmedTransactionsCache
solution: check both a multisig transactions inner and outer hash against hashes in the HashTransactionsCache

build and tag 0.6.100
