Add LICENSE-GPL file to repostiory

[blacklightpy]

Detailed steps on how to reproduce the bug

Clone/Download the repository.

Cloned repository doesn't have accompanying GPL license clause, only a non-free EULA.

What is the expected behaviour?

Either an explicit GPL license is provided by the project or the EULA clearly defines the scope of GPL instead of forcing anyone who uses the project to submit the rest of their lives to GPL.

Currently the EULA says you should distribute 'your programs' under GPL. It doesn't say 'our program' or 'your programs depending on our program'.

This problem was first noted by Void Linux team, who refused to package Helio Sequencer which was dependent on JUCE. I think that's a good problem to solve. My thread at the forum recieved no response.

Was planning to package this for MacPorts but ran into the same issue.
