[Newbies] Omnibrowser, italic Traits' method names

[Robert Krahn]

Hello Juraj

If you replace String with Text in  
OBClassSortFilter>>displayString:forParent:child: everything works  
fine. But thats quite dirty. I think something general should be  
changed with the handling of those displayString methods. On the one  
hand sometimes Text-objects are used (and needed for the attributes).  
On the other hand the variables which refer to those objects are  
named aString and sometimes they are Strings.

Best, Robert
