Logger refactoring

[pacmancoder]

expected result:

1. Logger should accept category parameters (subsystem e.g Server, interconnect + source e.g ParcelSerializer, SceneRenderer)
2. Logger should have filtering abilities
3. Logger log_* functions should be macro - to avoid calculations of parameters:

   log_debug(std::string("test").append(to_string(bigObject)));
   // will expand to the following pseudo-code
   if ( logLevel  >= Debug)
   {
   log(LogKind::Debug, std::string("test").append(to_string(bigObject)));
   }
