DFM: Dev-Fee Modifier

Dev-Fee Modifier brings the control of a miner dev-fee back to you! This ensure that you have full control over your own software, and allow the users to monitor if the fee is higher than advertised.

Depending on the configurations, users can completely remove dev-fee if intended. The choice is yours.

This software is still in beta vesion, contributions in the form of coding or donations are very welcomed.
