[Evolution] Replies to text + html e-mail

[Adam Tauno Williams <awilliam opengroupware us>]

I only send text/plain e-mail.  But I get lots of text/plain + text/html
messages.  But when I go to reply to these messages Evolution still
seems to be replying to the text/html part and not the text/plain part;
for instance quoting is weird, occasionally there are unremovable blank
lines, etc...  Editing the reply message can be frustrating.  Is there a
setting to reply using the text/plain part?
