bb8456691b Avoid overflow in UnitMotion. 
ComputeTargetPosition called Dot() with large enough vectors that it
overflowed. Avoid that by not actually doing the full dot product.

c219ee54b2 Move "IsInRange" family of functions to the Obstruction Manager and make the commutative. 
These functions were placed in UnitMotion, which had nothing to do with
range checks and made them available only to moving entities for no
particular reason.

This patch also adds support for square-square range checks and
shape-shape distance checks.

Modified from a patch by bb on top of work from wraitii.

03d2c5e40b Support inverted goals with the long-range pathfinder. This allows units to flee and should fix problems with ranged units too close to their targets. Fixes #3405, refs #3372. 
Now that units flee it's necessary to fix the unit chasing: this commit
reintroduces some code from 298115f4c5 that disappeared with the
committing of the new pathfinder. Refs #1537.

Also includes some style improvements to the UnitMotion code.
