- Cleanup [1786], which went in with unfinished stuff by accident....

- Cleanup [1786], which went in with unfinished stuff by accident. - Revert [1785] and replace it by installing our own quitter in place of the builtin (for all py versions). This obviates the need for [1785] and gives a cleaner exit. - Fix ipdb to work with python 2.5, and update ipdb color schemes with %colors. - irunner improvements, mostly for use as a doctest runner.
