Subject: (svn r17214) -Add [NoAI]: GetAPIVersion() as optional function in
 info.nut. Return "0.7" to get an api compatible (as much as possible) with
 the 0.7 api or "0.8" to get the latest api. -Change [NoAI]: move all
 deprecated functions to a separate squirrel script that is only loaded if an
 AI requests an old API version.
