Z-Wave Exclue / Include in openHAB 2.1.0.SNAPSHOT with Habmin

I propose to remove this limitation -:

Justification/use case for this: Even if a thing is not managed - ie it’s configured through text files - the user may want to update configuration for the duration of the session. Currently this is impossible - configuration of the thing must be undertaken through the text file, which means the thing is reinitialised (removed, and re-added).
