Subject: [PATCH] neomutt: minor cleanups

 - neomutt has changed the binary name so we enable "mutt" via a wrapper script
   with a warning
 - we don't have to manually run the prepare.sh script as autoreconfHook handles
   everything for us
 - doc generation was previously trying to fetch DTDs from the net
