Attack Task Fixes

The recent attack task fix to prevent mobile units charging to their death exposed some other issues with the attack task and multi-threaded updates.

The previous implementation of the attack task would accidentally require mobile units with ballistic weapons to move towards their target prior to setting a weapons target even if they were in weapons range.

This was most obvious with the commander ubercannon (d-gun) where the commander turns or moves towards the target.

Without a weapons target the weapons task could not iteratively calculate ballistic firing solutions for either high or low arcs.

Meanwhile the attack task would be waiting for a firing solution during the first tick which would never be calculated.

The second tick of the attack task would then create a move task even when in range assuming no ballistic firing solution could be calculated and the unit needed to move closer.

The third tick would be waiting for the move with the weapon firing no early then the fourth tick.

The original implementation would also create a move task with a target goal based on 50% of the existing move range causing units to charge to their death even when in range.

This was most obvious with grenadiers, hornets, etc.

A small move distance or failed move might also stall the task by not setting the weapon target.

This was most obvious with the commander ubercannon (d-gun) where the minimum commander movement was too small at close ranges.

The attack task now sets the weapon target as early as possible when in range to allow for parallel calculation of a firing solution and only moves units their minimum navigation distance when required to keep them at range.
