-The settings handler now creates the graph BEFORE instanciazing the
nodes daemons.

-Started working on Network events (crash/restart node, delete sn, and
so forth)
Added a custom event "instant" that is executed imediatly after the
current one.
Usefull for intializaion in wich there are many changes in the graph.
Since that it enables to be only 1 "refresh" instead of beeing N
refreshed per N changes. (In one event)
