Mantis#1207. Thank you, TGlion for a patch that addresses:

Implementation of llModifyLand() and There is a bug on 
permission-check of land-terraforming: x an y-coordinates 
are interchanged on function-call ExternalChecksCanTerraformLand.
Correct: x is west, and y is north. 2) Missing check of 
"Other allow to terraform-flag" (Parcel.ParcelFlags.AllowTerraform)
