Fabio Alessandrelli 9e303ef71c WebSocket module now uses wslay library.
Both client and server are supported on native builds (as usual).

SSL server is still not supported, but will soon be possible with this
new library.

The API stays the same, we just need to work out potential issues due to
this big library switch.
