mutt-sidebar-patches-jplenz

Julius plenz's excellent cleanup and rework of the sidebar patches (kudos Julius!).

See http://blog.plenz.com/2012-01/mutt-sidebar-patch-improvements.html for the complete story.

The consolidated patch available here is an amalgam of 20 distinct patches that Julius wrote which essentially make sidebar performant and usable. An additional patch from me fixes a build squiggle with homebrew.

Why this consolidated patch ? Well, it's for homebrew primarily.

All credit for these patches goes to Julius alone.
