LICENSE: Move moral precisions to README.md to be OSI compliant and rephrase to avoid any limitation but at least make things clear and written.

Fix #1514.

Precisions made to the LICENSE were not legal modifications to the License, just some moral precisions since things don't seemed clear for everyone.
(Won't elaborate on this, but were some reasons add these precisions).


These precisions are just willing to protect the work of the community/developers and allow the project  to continue being developed with a
BSD 2-Clause License: ie share almost everything that is developed, without even thinking about potential business opportunities.

Since moral aspects seems to be modifying the license, these are just integrated in the README.md and are still a condition to:
- Expect the community to be welcoming.
- Expect free or even paid support (moral/integrity is more important than $$$ for us).
- Expect the contributions to be accepted/integrated.

So if you don't want to respect the moral precisions, up to you to use the project, but please
be coherent with yourself and don't use our time/energy; just improve/implement things by yourself :)
