[Etoys] Translating projects

[Bert Freudenberg]

One thing I thought about was making a Text object be translatable  
itself - when switching the locale we would store the previous  
translation in a dictionary (in a property of the object). Then the  
text could be edited, and when switching back, the old string would  
reappear. Hopefully we could make this behavior be the default, but  
it should be disabled from the halo menu, which could also show the  
other translations in a submenu.
