Build 218

[tim arnot]

Please Rebuild Your Databases!

* Added runway surface types for MSFS
* Added taxiways for MSFS
* Added aprons for MSFS (currently disabled because it busts the 32-bit memory limit, and PG can't be 64-bit because SimConnect)
* Improved progress updates during MSFS data scan
* Reordered db table generation
* Fixed VSI inop (data was in ft/sec not ft/min)
* Fixed Turn Rate indicator inop (data was in radians not degrees)

MSFS Still to do:
- Runway surfaces
- Taxiways
- Aprons
- Departures
- MagDev / WMM
- New PLN file stuff
