Title: Element paths

Adds path-finding support for the editor and engine.
* pathfinding is performed in the engine. A* is used, generating new nodes on the fly via line intersection.
* test functionality using PathTester (in desktop editor tests)
* still requires polygon editing to be used from the editor; see ShapeEditor (as above) for a candidate
