* refactored send_INTERNAL_1packet and ClassB_send moving most of the encoding logic into the ClassB_send
* ClassB_send can now take an arbitrary byte vector as a raw packet of master protocol data, it will divide this into chunks for multisig outputs, pad where necessary, obfuscate them and handle all the other stuff like sequence numbers and ecdsa code points.  Most of this was already around in various forms
* Added a new RPC call that can take an arbitrary hexadecimal string along with addresses and construct a master protocol transaction for the network.  There is no error checking on the contents of this string and it basically becomes a thin wrapper for a generic ClassB_send
* fixed an issue with a fresh copy of mastercore not properly initializing the sp database due to the lazy init on the genesis block being called before mastercore_init
* added a script to illustrate a raw tx
