(commit by Kelly Bunn)
session.py: Created method (sendnodeemuid) to send node status response
message, so all nodes can call it. Added per session updown
script option.
service.py: Added test for _starttime before calling float() in
bootnodeservices().
Changed servicesfromopaque code to collect unknown
services and return with valid services.
Changed handleevent to send a message with posible failed
and unknown services.
coreobj.py: Added code to put nodes actual configured services in
tonodemsg.
core-daemon: Added call to self.session.sendnodeemuid if in running
state in handlenodemsg
