[Cheat Detection] Anti-Cheat reimplementation (#1434)

Browse Source 
* [Cheat Detection] Anti-Cheat reimplementation

* minor patch fixes

* ceiling to server side runspeed

Warp(LT) was picking up a bunch of expected 6.2 but it was reported back as 6.5, this should help reduce the amount of false positives we get

* use ceil instead of std::ceilf for linux

* boat false positive fix

* stopping the double detection

* fixes and cleanup

* auto merge tricked me...

* dummy divide by 0 checks

this should prevent anyone from setting Zone:MQWarpDetectionDistanceFactor to 0 and causing a crash.

* Formatting

* encapsulation to its own class and clean up

* more detections

* typo

* OP_UnderWorld implmentation

* Update client_packet.h

* Syntax changes, formatting, cleanup

* preventing crashes due to invalid packet size

* typos and clearer logic

* seperated the catagory for cheats

* Updated MQGhost for more detail
