Lightweight JSON RPC wallet compatible with bitcoind

• same commands and same result as bitcoind JSON-RPC API
• no need to download the blockchain
• usable as a python library to develop your own wallet
• usable as command line wallet (without json-rpc)
• private keys are crypted with the same algorithm as wallet.dat
• sqlite database easyly usable with all languages and commmand line client
• and off course compatible with counterpartyd

• v0.1
