Merge branch 'text-quote-to-html-div'

* text-quote-to-html-div:
  Use property to determine if we should write test debug information or not.
  Remove top margin on converted quote text, consistent with html quoted text.
  Colorize quoted text that has been converted to html. Like Thunderbird, but optimized for mobile (no right margin quote bar, thinner left margin quote bar).
  Add 1ex of margin at the bottom of converted blockquotes.
  Convert quote characters in plain text messages to blockquotes in the html version.  "Be like Thunderbird."
