[evolution-patches] Preserve headers in display.

[David Woodhouse <dwmw2 infradead org>]

Another UI fix... this time to make Evolution preserve headers when
parsing an incoming mail. Again a pair of before/after screenshots
showing the improvement:

	http://www.infradead.org/~dwmw2/evo-preserving-headers.jpeg

The parser already had an option to behave like this, preserving
information, but it was buggy, which may well have been why it was
disabled. This patch both fixes and enables it.
