Added LGPLv3 to top-level of repo.
This is a possibly controversial MR. Feel free to reject.
At the moment, we say that 'you should have received a version of the LGPLv3 with this software'. We do not currently distribute a copy of the LGPL. We distribute a copy of the GPLv3 with our COPYING text file.
I propose that we either:
- Move COPYING to LICENSE.md and include a markdown version of the GPLv3, or
- Remove COPYING and leave this version of the LGPLv3.
@pdraper @matthieu @nnrw56 please could you comment on this.
