Subject: add Nasal/Listener hooks for adding/removing AI/MP models. Things like
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=79abf11466f6cccd0e383e04273997056c97da58;p=flightgear.git

add Nasal/Listener hooks for adding/removing AI/MP models. Things like
MP chat or Nasal/xml based radar instruments need that. It uses fgSetString,
because this is in a very "cold path" and shouldn't clutter the AIBase.
