Make the miner work in parallel and add mining output

[dangershony]

I decided to help improve this repo here is a parallel miner branch

[dangershony]

How to use?
Clone the branch here https://github.com/dangershony/xds/tree/parallel-mining

git clone https://github.com/dangershony/xds.git
cd xds
git checkout parallel-mining

And run the wallet normally as per this instrucitons #2

An additional config parameter was added -minethreads=1 to set the number or processors to use.

BTW you can clone and checkout in one command:

git clone -b parallel-mining https://github.com/dangershony/xds.git

Also, if you only want to clone the branch then add --single-branch

git clone -b parallel-mining --single-branch https://github.com/dangershony/xds.git
