Bug#736413: [xmds-devel] missing licenses in debian/copyright

pygments.css is generated by Pygments, which is under a 2-clause BSD license: https://bitbucket.org/birkenfeld/pygments-main/src/3e451a3806d9215bae592d9c28321076e5e046ef/LICENSE?at=default

The generic ones are produced by Sphinx, and the XMDS-specific ones are released under GFDL.

I have removed documentation/latex in our buildscript for release versions.  It will not be there in future versions.  The built PDF documentation will be in documentation/xmds2.pdf

I have rewritten the offending code, which I release under the same license as the rest of XMDS2, i.e. GPL2.
