Title: Show rich message by default (if available)

To me this seems as a more useful default than to show a "first" mail part (usually plaintext if both plaintext and rich parts are provided). This is because I need more back-and-forths to tweak complex HTML layout than I need to tweak plaintext email copy.

This would also fix issue #37.
