-> Path Select Tool

Added a new tool to the 'W-Key' popup menu in mesh editmode, 'Path Select'.
When exactly two vertices are selected, 'Path Select' will find the shortest
path of vertices between them. There are two methods for determining
the shortest path, one that finds the path with shortest physical
distance, and one that finds the path with shortest topological distance.

Examples:

Path Select - Topological

The tool uses a straightforward implementation of Dijsktra's algorithm
and may be a bit slow on extremely large meshes. As a speedup you can
hide the parts of the mesh that you are not working on and they will
not be searched.
