QUASAR: Suppress ERROR log when receiving shutdown message

This message is expected in many contexts, such as when trying to connect to
novad when it is down. Thus this is not an error case at all. Also, since
Quasar doesn't need to do anything in this case, an empty handler is
placed to cover it.
BUILD: Put rm ~/.config/nova back in the makefile for uninstall-files target
Merge branch 'integration' of ssh://helios/home/git/repositories/Nova into integration
Merge branch 'integration' into pulsar
LIB: Fix bug where doppelganger interface string blank and crashing honeyd

Actually two bugs. One was that the interface string was blank because
the Config.h file had some changes and the GetDoppelInterface method
was giving back the wrong variable, one that was never set.

The other problem was that editing the interface and ip of the doppelganger
node in the node editing page wasn't changing the values in NOVAConfig.txt. 

Ticket #749
