Add www() for searching on the web

[aroberge]

As suggested in https://pythonbytes.fm/episodes/show/220/what-why-and-where-of-friendly-errors-in-python, perhaps I should add a www() function that would search for a corresponding error (type and message) on the web. This could be done using Python's webbrowser module and searching on duckduckgo (for privacy).

Also perhaps add a special function to search Python docs; perhaps py_doc() which, by default, would search on the error name on the python site but could have a special field linking to a specific place. Since the python docs are also available in French, it should link to the appropriate version.

Before I can create the py_doc() function, I need to restructure the "back end" and change the return argument of probably close to 100 functions (which is something I was planning to do, but is getting a higher priority).

www searches for the error message. If no exception has been raised, it simply searches for Friendly-traceback ! 😄

Closing this issue. Much work needed for custom links, but both www() and py_doc() work with the existing information.

Removing py_doc() and adding a python keyword to www() instead. Also added another argument to search for a specific term.
