Changed ray test to use the player's movement direction instead of forward direction when checking for collisions. Added ray drawing function that directly takes ray origin and directions as params instead of ray struct

 Todo:
-	- Improve player collision by impelenting sliding along collision plane in case of collision
+	- Bring back sprinting
+	- Fix aggressive frustum culling when camera looks up and the object right infront of the viewer gets culled
 	- Check if running in a lower frame rate affects movement
 	- Move player movement related variables from function to player struct and load them from config file
 	? Write entity flags to scene file or when saving entity to file?

 	* We no longer keep geoemtry data loaded from files as it is not needed after data is passed on to opengl
 	* Shift-A to add entity to scene
 	* Fixed crash where if an entity is hoverd in editor and deleted, the game crashes because the hovered variable in editor doesn't know that the entity was deleted
