Switchmaster UI should send only changed data

[atonkyra]

Switchmaster currently sends full object when updating configured->unconfigured (or vice versa) or when updating the switch location.

This leads to a race where user1 changes switch to unconfigured. Simultaneously user2 changes switch from stationed to at storage which overwrites the unconfigured state back to configured since user2 did not (yet) get the statechange by user1.

Last commit wins when manipulating the same value but the manipulation must be scoped to the value that is being changed and not to the whole "switch" object.

Issue can be (temporarily) worked around using following patch pending final fix.
