issue2550799: provide basic support for handling html only emails Initial implementation and testing with the dehtml html converter done. The use of beautifulsoup 4 is not tested. My test system breaks when running dehtml.py using beautiful soup. I don't get the failures when running under the test harness, but the text output is significantly different (different line breaks, number of newlines etc.) The tests for dehtml need to be generated for beautiful soup and the expected output changed. Since I have a wonky install of beautiful soup, I don't trust my output as the standard to test against. Also since beautiful soup is optional, the test harness needs to skip the beautifulsoup tests if import bs4 fails. Again something outside of my expertise. I deleted the work I had done to implement that. I could not get it working and wanted to get this feature in in some form.

Debugging Aids
--------------

Try turning on logging of DEBUG level messages. This may be done a number
of ways, depending on what it is you're testing:

1. If you're testing the database unit tests, then set the environment
   variable ``LOGGING_LEVEL=DEBUG``. This may be done like so:

    LOGGING_LEVEL=DEBUG python run_tests.py

   This variable replaces the older HYPERDBDEBUG environment var.

2. If you're testing a particular tracker, then set the logging level in
   your tracker's ``config.ini``.

SENDMAILDEBUG
=============

Set to a filename and roundup will write each email message
that it sends to that file instead to the internet. 
This environment variable is independent of the python -O flag.
