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.
