Summary: enhancements for cgitb

Initial Comment:
Since the module is short and some code got rearranged, the
patch is longer than the module.

Enhancements:
    - file URL now starts with "file://" (standard) rather than "file:"
    - new optional argument 'context' to enable()
    - repeated variable names don't have their values shown twice
    - dotted attributes are shown; missing attributes handled reasonably
    - highlight the whole logical line even if it has multiple physical lines
    - use nice generator interface to tokenize
    - formatting fixed so that it looks good in lynx, links, and w3m too

Tested under varying conditions:
    - with or withour 'display' turned on
    - with or without 'logdir' specified for saving files
    - pydoc module missing (still prints text traceback)
