Pathfinding API v0.5 released

The big news with this release is that, like any good open source project, the code is now platform independent. I finally acquired a Linux box to test with - my PS3 running Debian.

The other updates are:

Transformable waypoint collections (WPCs) are now incorporated into the pathfinding algorithms. WPCs are inserted as subpaths when a pathfinding algorithm reaches a bin solely occupied by an obstacle with a corresponding WPC.

Added debug and release configurations that remove the library's TinyXML dependency if WPCs are not used.

A demo for 0.5 is in the works.
