Summary: Improve exception pickling support

Initial Comment:
Due to various issues with how pickle works and new-style classes, pickling exception objects has been somewhat unreliable since Python 2.5.  See comments in patch #1692335 for more detail.  Attached is a patch that seems to improve pickling exceptions to support various different types of subclasses.

It has some limitations (exceptions that use __slots__, doesn't fully support SyntaxError, UnicodeError, SystemExit, or WindowsError).  However, it is an improvement for my situation.
