(svn r16365) -Release: 0.7.1-RC2

- Fix: The previously selected NewGRF station type was still remembered after switching to a different game without newstations enabled, preventing stations from being built (r16363)
- Fix: Pointer incremented with wrong count (r16361)
- Fix: Delete invalid depots in TTD savegames caused by improper SVXConverter conversions (r16357)
