All ships now have their own properties, which are modifiers for the base ship properties.
The base behaviour of all ships can now be easily changed, while the individual differences are still respected.
Ship states now trigger particle emissions & effects. This is still messy and mixed with
sounds. Will be overhauled once ship state machine is introduced.
To calculate gravity you now need to specify the gravity source transform.
