Insert full license text
Review Request #128780 - Created Aug. 27, 2016 and submitted
Put the full BSD3 license text into all files.
The reason is because I am using some ECM stuff in non-KDE projects and it's a pain to replace the text in the copied files. I'd rather have it done once and for all in the real ECM package and this way I won't forget to replace the text as required
make test still passes 100%
