Third pre-release patch

The following changes are now live:

• Fixed map height reading to be more consistent when laying track

• Fixed potential null reference crash in mouse scroll handling

• Fixed signal routing problem causing switches to be set incorrectly

• Fixed Map 3 max industry levels and added track pieces on home platform

• Fixed radius calculation for min radius achievement to also take actual radius into account

• Fixed signal adding to not work when map doesn't have signals

• Fixed getting stuck inside a wall on foot

• Removed grade matching. Changes to the grade setting will no longer be overridden when running on existing track

• Changed collisions to other objects on foot to be less sticky

• Improved German translations (thanks Bravura Lion)

• Added teleporting by clicking on the map. You can only teleport to your own tracks (but the map doesn't show them yet)
