(svn r15095) -Add [NoAI]: allow AI Libraries to be in .tar files (subdir required, as with AIs

Browse Source 
-Add [NoAI]: allow multiple versions of the same AI co-exist
-Change [NoAI]: updated the whole method of AI (Library) finding and loading; it is now much more clear and transparent
-Change [NoAI]: the name of the AI is now the name used by CreateInstance()
-Change [NoAI]: make the AI finder a bit more clever, mostly related to version finding
