Fix for the Windows Server lag issue

[peterigz]

Hello, regarding the lag issues with some Windows Platforms (http://www.eqemulator.org/forums/showthread.php?t=42311), it looks like for some reason Windows Server tripped up over itself when using LibUV in a while loop with UV_RUN_NOWAIT and is much happier with UV_RUN_DEFAULT. Here's the commit: https://github.com/peterigz/Server/c...d9354b846bddb0

Currently running this on The Hidden Forest and all lag issues have now been resolved, 18 would lag heavily for us and drop clients, so far we've had 50+ in zone with no problem, hopefully we can stress test with more soon but either way it's way better then it was.

I'll give it some more time in case any other issues arise, then I can do a pull request. I can't check Linux, maybe someone can build on that platform to see if all still ok there, can't see any reason why not.
