Subject: [PATCH] Improve RPC errors Display

Example with new formatting:

  sendrawtransaction RPC error -22: TX decode failed. Make sure the tx has at least one input.

Instead of:

  sendrawtransaction RPC error -22: {"code":-22,"message":"TX decode failed. Make sure the tx has at least one input."}
