HomeCtrl adapted to new Com bundle 2.0

Yesterday I pushed a new version of HomeCtrl to GitHub. What's new? I adapted HomeCtrl to the new Com 2.0 bundle. There is no new functionality. I also pushed a change in the com project. The communicator gets a RX scheduler now instead of an ExecutorService.

I pushed HomeCtrl on a new devel branch. Later today, when I don't see any errors at home, I'll push it on the master branch. Then I'll also push Com 2.0 on the master. So it's release of the new library today, yay :).
