[PyCrust] Recent Changes

[Patrick K. O'B. <po...@or...>]

I've changed the way that PyCrust determines the object for which 
autocompletion options and calltips should be presented. The new way 
uses the tokenize module (plus the usual jumping through hoops that I 
always have to do) and does a better job supporting whitespace within 
commands and empty types: '', "", '''''', """""", [], (), {}.

The new version passes all the old unit tests as well as some additional 
unit tests. What I'm not sure about is whether it interferes with 
anyone who is using PyCrust for non-standard code. In particular, I'm 
worried about you, Raul Cota. :-)

Anyone who relies on autocompletion for commands that aren't pure Python 
code should get the latest PyCrust from CVS and make sure I haven't 
broken their application. If I have, let me know and hopefully we can 
figure out a solution.
