Planned CBTT Core Update.

I'm looking into switching the CBTT core from using the select() function for socket handling to the boost::asio (Async Input/Output)

Hopefully, any socket issues left over will be eliminated with this switch, and load issues will become nonexistent.

And for those XBTT zealots. Let's see some side by side benchmarks before you go touting that XBTT is better.
