MPD: follow symlinks, thus removing duplicates from DB

I run into a problem with git-annex repo (in indirect mode) as a music
directory: MPD stored both a symlink and an actual file in the DB,
making every song show up twice.
MPV: start in fullscreen mode
Mutt: add a mailbox for arbtt mailing list
Newsbeuter: subscribe to a couple more feeds
Keep 14 daily backups instead of 7
Tmux: propagate window name changes up to terminal
ZSH: show tmux session name in the window title
Vim: don't un-indent # in awk scripts
ZSH: create netassist tunnel upon login
ZSH: provide find_original to find files that are hardlinked

I often hardlink stuff into annex dir, because I both want it in the
annex (for preservation and synchronisation purposes) and in its
original place. Before dropping stuff, I run this alias to find out
where hardlinked files reside, so I decide what to do with them now.
Set up arbtt
XMonad: provide finer granularity for volume adjustment
Ignore some new stuff
