Add a LICENSE file

[Exordian]

Hi Oliver,

thanks for the collection of scripts!

As I couldn't find a license information, I'd kindly ask to consider adding a license file. Without a license it's unclear from a legal perspective how to use your collection.

Another repository is already licensed under the MIT License: https://github.com/okieselbach/SyncMLViewer/blob/master/LICENSE
