floBlockchainAPI v2.4.1: Improvements and signTx

Browse Source 
- Added createTx: create unsigned tx (resolves tx-hex )
- Updated createMultisigTx: resolve tx-hex instead of tx object
- Added signTx: (synchronized fn) sign the given tx (hex or object) with given private key and returns the signed txhex
