mutt: Update to version 1.12.0

Changes since version 1.11.4:
! $ssl_use_tlsv1 and $ssl_use_tlsv1_1 now default to unset.
+ $auto_subscribe, when set, automatically adds an email with the List-Post
  header to the subscribe list.
! Fcc now occurs after sending a message.  If the fcc fails, mutt will prompt
  to try again, or to try another mailbox.
+ Basic protected header ("memory hole") support added for the Subject \ 
header.
  See the config vars: $crypt_protected_headers_read,
  $crypt_protected_headers_save, $crypt_protected_headers_subject,
  and $crypt_protected_headers_write.
! Color names can be prefixed with "light" in addition to \ 
"bright".  "bright"
  colors are bold face, while "light" are non-bold.
! Color commands can now include an attribute (e.g. bold, underline).
! $pgp_use_gpg_agent defaults set.
+ <descend-directory> in the browser menu allows entering nested maildir
  directories.
+ <group-chat-reply> replies to all, but preserves To recipients in the reply.
+ $include_encrypted, default unset, prevents separately encrypted contents
  from being included in a reply.  This helps to prevent a decryption oracle
  attack.
! With gpgme >= 1.11, recipient keys with a trailing '!' now force subkey use,
  as with classic gpg.
! In send mode, %{charset} mailcap expansion uses the current charset of the
  file.
+ $imap_fetch_chunk_size allows fetching new headers in groups of this size.
  This might help with timeouts during opening of huge mailboxes.
  If you have huge mailboxes, you should also try $imap_qresync.
! <toggle-write> can be invoked from the pager too.
+ The $forward_attachments quadoption allows including attachments in
  inline-forwards (i.e. $mime_forward unset, $forward_decode set.)
