Multisig protocol parameter limit

Currently, the implementation in #1102 allows for an arbitrary amount of signers on an established address. To prevent time and cost escalation we should hard limit the number of public keys associated with an established address.

Hmm, wouldn't this be effectively limited by the gas limit though?

It would, but it could be a DDoS vector anyway
