[tycho-dev] Update demo application

["Oberlies, Tobias" <tobias.oberlies@xxxxxxx>]

I've verified Jen's update to the RCP demo project - it works as expected with the staged 0.11.0. It is available here: https://github.com/oberlies/sonatype-tycho/tree/demo-update-0.11 (with some unnecessary configuration removed).

I would suggest that we add this commit to the Tycho-0.11.x branch. I'd put it there (in addition to master) because it is documentation that should be part source code state tagged as the release. Since it is not part of the binary release, we don't need to re-stage 0.11.0 as consequence of this change.

What do you think?

Regards
Tobias
