Improve deployment of realease artefacts to Maven Central

[bwolff]

As far as I understand, the deployment process of the release artefacts to Maven Central is still a separate (internal) process. It seems that nowadays it's possible to deploy directly to Maven Central using Tycho.

Since I only consume the RWT dependencies from Maven Central in my project, I can offer to have a look into how to improve this process, so it could integrate better into the regular release process. In this case it would be nice if you could share some insights in how it is currently done and where it should probably be integrated (e.g. in the RAP builds?).

Best regards, Ben
