(svn r27432) [1.5] -Backport from trunk:

- Fix: When selecting a refit cargo for orders, do not check whether the vehicle is in a depot or station, and do not ask whether the vehicle currently allows station-refitting. Also hide the refit cost for orders, it is not predictable (r27428)
- Fix: Use the NewGRF railtype sorting order in the infrastructure window (r27427)
- Fix: Crash when switching to or taking over companies, when an order window of a vehicle of the new company was opened. Now close those windows [FS#5842] (r27425)
- Fix: Towns did not connect roads to existing roads, unless they had only a single roadbit. Otoh, towns also tried to connect to single roadbit tiles such as tunnels and depots, even though they were not connectable in the direction of interest [FS#6374] (r27424)
- Fix: When towns expanded single-bit roadtiles using a grid-layout, they used the layout position of the neighbouring tile (r27423)
- Fix: Aircraft picked the wrong airport entry point, if airports were rotated by 180 degree [FS#6341] (r27422)
