Move licenses to LICENSES/, use SPDX-License-Identifier, mention all licenses in galaxy.yml (#430)
* Move licenses to LICENSES/, use SPDX-License-Identifier, mention all licenses in galaxy.yml.

* ignore.txt lines cannot be empty or contain only a comment.

* Cleanup.

* This particular __init__.py seems to be crucial.

* Try extra newline.

* Markdown comments are a real mess. I hope this won't break Galaxy...

* More licenses.

* Add sanity test.

* Skip some files, lint.

* Make sure there is a copyright line everywhere.

* Also check for copyright line in sanity tests.

* Remove colon after 'Copyright'.

* Normalize lint script.

* Avoid colon after 'Copyright' in lint script.

* Improve license checker.

* Update README.md

* Remove superfluous space.

* Referencing target instead of symlink
