raise signal "/sim/signals/nasal-dir-initialized" when all Nasal files

in $FG_ROOT/Nasal/* were loaded and executed, and thus all Nasal library
functions are available. This was in the past only done with settimer(..., 0),
constructions, but suchlike triggered timer functions are executed
*after* aircraft specific Nasal files were loaded, so they can't be
used for internal library initialization, where e.g. props.Node() is
already needed.
