Split path finding out of the Map class

Extracted the path finding algorithm out of the Map class and introduced
a new class called PathInfo that has the path finding information that
used to be part of MetaTile.

This allows a single vector of path information to be shared between all
maps running on the server, significantly reducing the memory overhead
per map (for 200x200 maps, the memory reduction is about 1 MB per map).

Part of this change is some cleanup, like moving the 'occupation' counts
into MetaTile, inlining some methods for performance reasons, and using
STL to simplify memory management.
