* AbortOnResupply will now cancel queued activities
in addition to the current attack.
* Resupply if no ammo is available during a standard attack.
* Don't resupply (move directly to target) if no ammo is available
during an attack move (C&C3 style).
And polish CanHover FlyAttack behavior:
- Get rid of direct TickFacing usage
- Fix that the CanHover facing/altitude update would override
TakeOff child of Fly
- Streamline the queueing of child activities
- Get rid of a direct FlyTick in favor of relying on Fly activity
- Pull queueing of TakeOff out of the if-else
