Copyrights had become ads for Sustrik's corporate sponsors, going against the original agreement to share copyrights with the community (that agreement was: one line stating iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads is also unfair to the many individual authors. I've removed ALL corporate title from the source files so the copyright statements can now be centralized in AUTHORS and source files can be properly updated on an annual basis.
