i1673 implementation of py3 proper error handling...

i1673 implementation of py3 proper error handling I refactored ultratab.py a bit. `structured_traceback` function was much too long. I extracted some of the code to separate methods. I added support for py3 exceptions which store information about previous exceptions in their `__context__`.
