mutt-patched: sidebar keybindings

mutt-patched it's really cool, thanks Myon for advertising it. Actually I've tried it only in the hope that it could solve Debian bug #459739 (don't bother trying: it doesn't), but I'm now liking it, especially the sidebar patch.

Unfortunately it lacks default keybindings for moving the sidebar cursor (why the heck: since the sidebar is enabled by default, am I supposed only to look at it?). Here are mine, in case someone wants a "plug and play" configuration for her .muttrc:

zack@aquarium:~$ cat .muttrc |tail -n 6
# mutt sidebar settings
bind index,pager \CP sidebar-prev
bind index,pager \CN sidebar-next
bind index,pager \CO sidebar-open
macro index,pager B '<enter-command>toggle sidebar_visible<enter>'
color sidebar_new yellow default

They are basically a subset of those proposed on the homepage, but I did not like changing the default semantics of b. See also Debian bug #459725.
