- Fixed: createTransaction not returning promise
- Fixed: script not correctly added for multisig inputs
- Fixed: signTx throwing syntax error
- Added checkSigned(tx, bool?): check if the tx is signed or not. (bool is optional, default=true, if true returns a boolean value, else returns a detailed array of input's length)
- Fixed minor bugs in lib.js
- Added createTx: Create an unsigned tx (no privkey required) [segwit sender not supported for now as redeem-script needed]
- Added createMultiSigTx: Create an unsigned tx for multisig address
- Optimised sendTx to reuse code (no functional change)
