Tx json

[theflyingcodr]

Transactions can now be properly serialised and deserialised as JSON.

This is achieved by implementing a custom marshaler and unmarshaler which will produce JSON as shown:

}

It also adds some new convenience methods to script to get the current type of script as a string and to return all addresses contained within a script (multisig support still TODO).

In the opcodes I updated all raw bytes to use the correct opcode constants to make it easier to read.

no need to check in the vendor mondules @theflyingcodr

[jadwahab]

@theflyingcodr yo i just realised this, don't think this should be in here... do you?

[theflyingcodr]

I think I was using this to track the vout, I'll need to double the code again as it's been a while!
