Initial work on TCP transport layer:

Browse Source 
* Optionally compiled additional TCP transport layer.
* Config to enable it.
* Tested and functional with lcdr's tcpudp dll, udp being disabled in the dll due to port issues.
* Removed unused RakNet replica manager and id manager. We've got our own replica manager since pre-open-source.
* Utilizes async boost behavior.

Todo:
* Figure out how to do ping calculations.
* Fix crashes on universe shutdown.
* Test TLS on a VPS.
* Remove unnecessary logging.
* Test with lots of clients.
* Finish "master" to "manager" naming refactor.
