mutt: tweak status_format
vim: set notitle

I often invoke vim via mutt in an xmonad scratchpad. The scratchpad is currently
managed by title. When vim changes the title, I can no longer dismiss/recall the
scratchpad. I have no need for vim to change the title, so this setting fixes
that with no downside.
