(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.
