[Adium-devl] Old keyboard layouts and new APIs

[David Smith]

	As part of the preparation for 64 bit Adium, I applied Rogue Amoeba's  
patch to convert PTKey* over to using the modern TIS* API rather than  
the deprecated (gone in 64 bit) KL* API. Unfortunately, it seems that  
TIS* doesn't support old-style kchr keyboard layouts. As such, you can  
crash Adium by doing the following:

1) Install a pre-leopard keyboard layout
2) Activate it
3) Open general preferences in Adium 1.4

	I'm a bit uncertain on what to do. I guess we could #ifdef in the old  
code, but that's sort of horrible. I'd prefer to just fail gracefully  
somehow. Still looking into how to go from "TISGetInputSourceProperty 
() returned NULL" to something that makes sense in the UI.
