Fix settxfee need to convert amount to btc from satoshi
Fix for optional arg off by one in move.
Fix for gettxout in optional args along with typo in error message.
And lots of new tests.
Test stop, signrawtransaction, setaccount, sendtoaddress, and a few
others.
Fix off by one error in the optional arguments for sendtoaddress.
Rename occurances of Minconf to MinConf for constitancy.
This changes the behavior of ParseMarshaledCmd to always return a
non-nil Cmd whenever unmarshaling a valid JSON-RPC message succeeds.
This is needed for RPC server code to reply back with detailed errors
to clients using the Method and Id methods of the Cmd interface.
Initial prototype for one command mostly from jrick, with discussion
with me and jcv. Other commands mocked up in a couple of long boring days by
yours truly.
Code isn't fully tested yet so may well still be buggy in the type conversions.
Test will be added over the next few days to get this up to snuff.
