Removing dependency on Boost about simple-websocket-server

[eidheim]

Thank you for the kind feedback.

We are dependent on Boost in the next few years. However, Asio will most likely be a part of the standard library in C++20. We can also move to std::regex instead of boost::regex in around 2019. Boost.Coroutine is also used, but hopefully the boost.asio sources will move to std coroutines soon after C++17 arrives, but like with regex, we would need to wait for the popular server LTS'es to expire.

That said, I do try to keep the library as modern as possible, but I also have to take into account that older systems like, currently, Ubuntu 14 and debian stable should be able to compile the library without modifications.

Thank you for explanation.
That is ok, just wanted to know. With or without Boost, I am going to use your library.
BTW, great you have made it MIT licensed. Good choice.
Closing issue.
