create functions in main.cpp which can decode and strip NCC commands from a txout.scriptPubKey, and create functions in rpcwallet.cpp which can create transactions with NCC commands. change tests to pass given NCC parameters, add CLAIM_NAME as a script command in script/script.h, and add a few printouts that occur during transaction spends which should be removed later
