Red shell rework, they always instathrust to their top speed in their current movement direction.

Browse source 
When they get close their top speed starts to decrease to the player's current speed.
Movement direction ends up being adjusted in A_RedShellChase where it Thrusts towards the player at its acceleration speed.
