Changes

* Added FSF recommended LGPLv3 licence notices to the top of all of the extern.sobol files. Excluded is the auto-generated test output file.

* Renamed the LGPLv3 file in the extern.sobol package to <code>COPYING.LESSER</code>.

* Updated all of the relax deployment scripts for the Gna! shutdown. These now use the SourceForge sites for [https://sourceforge.net/projects/nmr-relax/ relax], [https://sourceforge.net/projects/minfx/ minfx], and [https://sourceforge.net/projects/bmrblib/ bmrblib] instead. The svn to git conversion is also taken into account, and git is used to pull in the latest relax code from the SourceForge mirror.

* Converted a large number of Gna! links to point to the equivalent Web Archive URL. Most of these links should have had a snapshot made in the Internet Archive Wayback Machine.
