automatic DAG pregeneration for smooth epoch transitions
- backend: AutoDAG bool flag passed from cli/eth.Config to ethereum, autoDAG loop started if true - backend: autoDAG loop start/stop, remove previous DAG - cli: AutoDAG bool flag, off by default, but automatically ON if mining - admin jsre: add startAutoDAG stopAutoDAG and makeDAG in miner section - switch on/off DAG autogeneration when miner started/stopped on console
