Set winapps as deprecated and link to winapps-org

[kikibase]

Just to prevent people from going through all the installation and realizing this version isn't supported anymore.
Thank you.

Hi @kikibase,
Unfortunately, as per #269, Fmstrat does not seem to be replying nor interested in making this modification.

I was helping my friend set this up today, and we got a good part of the way until we realised. Luckily the projects are still pretty similar so we were able to just make a few modifications to the VM settings and could use the forked version, but @Fmstrat should definitely add a note to the README.
