Improvements to stationary unit logic

[Starkku]

• Extended logic e.g Speed=0 to work on InfantryTypes.
• Speed lowered to 0 by multipliers will now prevent some of the logic from being executed (cursor, assigning destination etc. works but not actual movement).

---

Stationary units

• Infantry & vehicles with Speed=0 or those that are prevented from moving on their cell by MovementRestrictedTo are now truly stationary will not attempt to move if issued movement commands. Should not be used on trainable/buildable units as they become stuck in factory. Following behaviours apply:
  • Cannot retaliate if target is beyond their weapon range.
  • Cannot acquire units outside their weapon range on Area Guard mission.
  • Hunt mission is reassigned to Guard.
  • Units rendered stationary by speed multipliers instead of intrinsic properties of TechnoType will respond to cursor actions e.g assigning destination but will not move while the multiplier is in effect.

object info dump showed that these stationary units will sometime enter 'Move' mission for a short moment, then switch back to 'Guard' quickly without actually moving. Not sure if it's a desired behavior

[Refailure]

After applying an AttachEffect with SpeedMultiplier=0 to the target unit, the target unit can still rotate its hull once before it stops rotating the hull and only rotates the turret. Hover units can always rotate their hull.

And units that have performed the single rotation cannot load passengers.
