* Make CMakeLists support more than just g++
* Remove use of sys/time as it is POSIX compliance dependant and this is a multiplatform server
* Substitute in std::chrono as we are using C++11 anyway
* Include algorithm in Object.cpp as max isn't present without it (and remove the "std::" prefix as that file has a using namespace std anyway)
* Undef the min macro in PacketHandler.cpp as windows specific libraries define it
