Add the date to the CPack rpm package version

Updating rpms built from 'make package' has issues using the git hash since it isn't in a set order like svn commits, this lets it use the date to determine if the rpm is newer than the installed version.

Also updates the license text.

Fix T38541: sys.exit fails when blender is built as a py-module

Fix Editderivedmeshes vertices normals computation.

Those derived meshes (used in Edit mode) were using simple sum of neighbor poly normals to get vertex normals,
while everywhere else in Blender we use weighted sum of such poly normals.
