PCRaster-4.0.0 test version 2 released

I have released a second test version of the upcoming PCRaster-4.0.0 release. See the PCRaster 4.0.0 download page for more information. This version has a much faster numpy2pcr operation and we fixed a bug in the resample command. Unless an important issue is found with this release, the next release will be the final 4.0.0 release.
