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.
