I did some experiments with ActionSetFieldWidget. ... If you set the 
tiddler title field, it creates a clone of the tiddler. (no confirmation 
needed)
So changing the name and deleting the "old" tiddler imo will move a tiddler 
to the trashcan. This mechanism should work fine with a client - server 
version too. 

The other way around is more sensible. Since there may be a valid tiddler 
that can't be overwritten without confirmation.
So a hook might be useful here to check the existing tiddler and ask for 
permission to overwrite it.
