[PyCrust] Auto completion filters now available

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

I just checked into cvs some changes to support filters on the auto
completion lists.

To exclude attributes with a single underscore prefix:

shell.editor.autoCompleteFilterSingle = 1

To exclude attributes with a double underscore prefix:

shell.editor.autoCompleteFilterDouble = 1

To exclude both, set them both to true. You can set and unset these in the
shell to see how they work. Try them with the PythonCard proof.py sample
application, which has a lot of hidden attributes now.
