(svn r2281) - Fix: [ 1115204 ] [NPF] When pressing the goto depot button, trains will now also look behind it if there is no depot in front. If so, the train reverses immediately. This also work anywhere, not just at stations.

- Add: [NPF] Reversing inside of depots now has a penalty. It also applies to trains only, other vehicles shouldn't bother reversing.
- Fix: [NPF] When checking whether to reverse a train, the trackdir of the first loc was used instead of the last vehicle as a starting node for pathfindig.
	This might have caused some trains not reversing when they should have (or vice versa). Typo introduced when converting to GetVehicleTrackdir() in r2256.
- CodeChange: [NPF] Removed duplicate code by letting NPFRouteTjoStationOrTile() call NPFRouteToStationOrTileTwoWay().
- Add: [NPF] NPFRouteToDepotBreadthFirstTwoWay() to find a depot while also looking backwards.
- Add: It is now possibly to specify a path cost for aystar starting nodes.
