Refactor some things to make slightly clearer code
Change comments to use completely tabs
Add extra error checks to methods for helpful debugging and safety
Use a heap of waypoints during creation to be able to search for them to make links, to not freeze the game
Add a way to clear waypoints so that the methods don't error after more than one map load
Flip the ambush flag so that adding it will make the waypoint unable to be respawned at when the feature happens
Temporarily disable K_UpdateKartPosition so that it doesn't crash on map load
Basically just copied what I planned out months ago and put it into code for now
Also changed waypointcap to be made from MT_WAYPOINTs and definitely broke position in this commit from that.
