Title: Fix errors generating Python parsers.

- Use "self." when referring to an instance variable.
- Copy references to indirect delegates by copying references to
direct delegates' delegates.

This fixes issues I described at http://www.antlr.org/pipermail/antlr-interest/2011-December/043544.html and http://www.antlr.org/pipermail/antlr-interest/2011-December/043546.html, where references to delegate parsers are incorrectly defined (usually causing the parser to crash) though as I mentioned there may be similar issues in other languages.
