Feature Request: Better logs for debugging

[littlebenlittle]

I've been unable to get the miner to work in my test environment and the log messages aren't particularly useful. There should be some sort of documentation for what these mean and what might be causing them.

Connection to pool is refused. Funakoshi-Miner requires ssl port of pool.

It seems that for btg.suprnova.cc no ssl port is specified. If so
you can't mine with Funakoshi-Miner there. You can mine at
zen.suprnova.cc:3621 or zec.suprnova.cc:2242 or zcl.suprnova.cc:4142

[funakoshi2718]

I have notified suprnova about it.

[funakoshi2718]

I am happy to inform you that btg.suprnova.cc added ssl port 8817 to their btg pool.
You are welcome to use it.
