[#141] Add storage printing to ContractRegistry

Description

Problem: apart from printing a contract and its documentation we usually need its storage for origination. It's common for (nearly) all contracts, but this functionality is not present in ContractRegistry.

Solution: add a new PrintStorage action there. ContractInfo now specifies how to construct its storage inside command line options parser. It is optional and can be omitted if you think that initial storage is easy to construct manually. Unfortunately, we need a different CLI for this functionality because parsing of initial storage data depends on its name and Parser is not a monad. So we have one storage-NAME command for each contract called NAME. Additionally, we add runContractRegistry function which captures storage printing logic along with handling of all other existing actions.

We also update morley-ledgers and morley-multisig. Updating morley-multisig require adding ciCompilationOptions.

Also I have updated the way output is chosen, now we construct output file name from contract name by default.
