Change license text to point to "OpenLayers contributors", referencing

authors.txt file. In reality, MetaCarta does not own copyright to these files,
they merely have a right to distribute them under the license terms agreed to
by the contributors. At this point, there is no longer any reference to
MetaCarta as a copyright holder in the OpenLayers project, only to its
individual contributors via the authors.txt file.
