Incorrect inputs' transaction hashes handling

[lnovy]

TXIDs of input transactions are loaded from API in an incorrect byte order.

[ghost]

utxo txid's are in reverse order in case of https://coinb.in/api/, whereas https://explorer.bitcoingold.org they are not. so ,
@line 959 of coinbin.js

var txid = ((tx).match(/.{1,2}/g).reverse()).join("")+''; should be replaced by var txid = tx;
