Revert license changes between 1.08 and 1.10

This reverts the following commits:

    "fix xt\licenses.t" (c9446dd0ca2c183ee10a750eb84b87968e781a93)
    "add some comments to aid" (1f9655bd06cec5e2f8bf49800b1ba649afe8c4be)
    "Fix for RT-55594" (d965d3ee328721af6c42280ad2d094b66e440c4b)

The license changes between versions 1.08 and 1.10 break backwards
compatibility and generate META.yml files with incorrect and conflicting
information.  License versions must be maintained, not ignored.  For
example, gpl_2 is different from gpl_3 and they are not interchangeable.
