Allow entities to be affected by Status Effects from ranged attacks.
This implements a status effects receiver component (in a similar fashion to the damage receiver component). The plan is to further extend this component notably to handle graphical indication of status effects, and a variety of other effects.
Currently implemented: ranged attacks can inflict status effects that reduce HP over time.
This can be resisted by armour.
No units currently utilise this in-game but with proper graphics support that could be changed.
