[PD] Hide backslash escapes in symbol atoms

As I've written elsewhere: as simple rule could be "show what you type". 
In a list box (and many other objects) you have to explicitly type '\' 
to get a whitespace inside a symbol, so I think it's also fine to 
display it as such.

But what about object boxes, comments, [text] etc.? They all follow the 
same rules regarding whitespace (the user has to explicitly escape it).

The only exception are cases where you are dealing with a single symbol: 
symbol atoms and since Pd 0.52 also all GUI object lables resp. 
send/receive symbols. Here it doesn't make sense to show the escape 
character as it is really an implementation detail and doesn't add any 
value to the end user. It just looks ugly.
