WS30: Property configuration VPB

Browse source 
Configure the VPB elevation mesh via properties:

/scenery/elevation-mesh/sample-ratio controls the elevation
mesh sampling, allowing reduction in mesh size

/scenery/elevation-mesh/vertical-scale is just for fun and
scales the mesh vertically making mountains taller.

/scenery/elevation-mesh/constraint-gap-m controls how much below
airports etc. elevation vertices are forced to be.
