Changes between Initial Version and Version 1 of Ticket #940

initial	v1
1	1	1.) Right now, ships can turn on a dime very unnaturally. It would be an enhancement to the movement of ships to implement a turn radius, perhaps similar to the way the P-51 Mustangs have a turn radius(?). And if there is not enough room for the ship to use its turn radius, then it uses a 3-point turn similar to how one would execute a 3-point turn driving a car.

5	5	3.) This should perhaps be a totally different ticket, but an acceleration feature would be nice. Ships should have positive and negative acceleration. This could also be useful for ramming and perhaps for other units who have a running and charging feature.
