[TxMt] Snippet/Macro/Command editor

[Ben Jackson]

Hi all,

I just erased half of my macros after editing the Snippets panel and 
removing a bunch of bundles that seemed empty as they had no snippets. 
Alan, can you make it clear to the user that deleting a bundle in one 
panel deletes all of the macros, commands, etc for that bundle and not 
just the items in the currently selected display mode? Maybe provide 
some kind of confirmation dialog as well :)
