new library messages

[Mark Wieder]

Looking through some of the IDE's library stacks, I see handlers for the 
messages extensionInitialize and extensionFinalize. From the code in the 
handlers it seems that these are now standard ways to set up and tear 
down extension libraries, but I don't see the messages documented 
anywhere. Can I assume that the engine now issues these messages when 
extension libraries are loaded and unloaded? And that they should be a 
required part of extension library scripts?
