Revert "Add some very rudimentary support for handling html parts"

This reverts commit ed16edc94d6a50ca86ff1575d9ea6fb9168b2e81.

The performance hit is just far too severe, (threads with many HTML
messages make emacs stop and pause for seconds before displaying the
thread even if most of the HTML messages are entirely hidden).
