It's a function of NSOpenPanel, the underlying native dialog that 
supports the "open file" dialog on OS X. It doesn't have a "file filter" 
capability, and so it will only recognize hard-coded types that are 
passed to it, cf. py and txt files. "dat" isn't recognized, I tested it 
out. There's nothing to do here; it's an aspect of the native dialog.
