Ladder ready build Linux + Windows v0.4

Various significant performance improvements.
Added find_path_*_closer_than methods for pathfinding that stops when it's within x distance of the target.

Fixed auto_correct to actually do something (find closest pathable location).
Recoded find_low_inside code to use normal pathfinding code.

Ladder ready build Linux + Windows v0.3

Windows and Linux binaries that allow the library to be used in Ladder Manager, ai-arena and sc2ai ladder.

Example initialization of the pathfinder in sc2 4.10.
