This converts the KWSys license to a pure 3-clause OSI-approved BSD License. We drop the previous license clause requiring modified versions to be plainly marked. We also update the KWSys copyright to cover the full development time range.
We replace the test text in the kwsys.testEncode test to avoid the word 'Copyright'. This simplifies grep results for Copyright verification.
