	vocabularywidget.py 
Log Message:
okay, I actually hooked up the vocabulary directive and registry, so that 
we can do actual useful things with vocabularies. 

I also had to fix a call that could not be run due to a context wrapper, so
I had to remove all proxies, which is probably not the right thing to do.
Fred, could you look at this?

Finally, it seems that I am the first one that seriously plays with 
vocabularies, since it is impossible that vocabularies are usable as they 
were before this checkin. Furthermore, many parts of the framework are in 
a sorry state; for example the widget for the IVocabularyField requires 
really an implementation of ITokenizedVocabularyField and ITokenizedTerm. 
Why? This beats the heck out of me.

I really thought that after so many people told me they studied 
vocabularies and that I should have a look, that they also wrote some semi-
serious code in it. But this cannot have been the case. I think studying
means "I read the docs." in this case.

Vocabularies are definitely not in a ready state for the first beta and
need to be added to the to do. (I will do that, as soon as I have the bug 
tracker setup.)

Finally, I will check in some code tomorrow, which demonstrates how 
vocabularies work, in one of the most common use cases (in my opinion).
