OH2 Z-Wave refactoring and testing... and SECURITY

as a result of https://community.openhab.org/t/cant-get-the-zwave-binding-to-update-the-s2-switch-from-a-fibaro-fgd-212

Yesterday i changed from the snapshot build 1302 to this dev binding (19 june). I followd the first posts and got the network up and running in no time. I discovered something strange in habmin:

  1. Under group associations the lifeline is empty, while it does report and work as expected.(display error?)
  2. Associations group 4 contains two empty Associations. These associations are with full operational nodes, still work and where setup with the snapshot version. (display error?)
  3. When an Association is removed by habmin, an NPE is shown
