launch file ros start node and wait for it

# You can make use of launch-prefix feature like so:

<arg name="node_start_delay" default="1.0" />  
<node name="listener" pkg="roscpp_tutorials" type="listener" 
		launch-prefix="bash -c 'sleep $(arg node_start_delay); $0 $@' " />

# The problem with using just launch-prefix="sleep 1.0; " was that the node
# launching command was passed as arguments to 'sleep'
