v0.1.1

In addition to code structure optimization and efficiency improvement, this release has the following major updates:

• HACD Mining! It is more than 2x more efficient than the previous version, and can be connected to the same full node to form a computing power cluster of mining machines. It can also display the hashrate of HACD mining.
• More accurate and stable hashrate shows that the hashrates of HAC mining is no longer so random.
