Bunch 'o patches from Oswald Buddenhagen: 

i implemented some cool stuff (tm).
first, the long missing "create server-side missing mailboxes". -C now
creates both local and remote boxes; -L and -R create only local/remote.
second, i implemented a 1:1 remote:local folder mapping (-1) with an
optional INBOX exception (inbox/-I). the remote folder is specified with
the folder keyword (or -F switch) and takes precedence over the
namespace setting. the local directory with the mailboxes can now be
specified on the command line, too (-M).

another patch:
- made the -1 switch settable permanently (OneToOne). after all, you
  usually define your mailbox layout once forever. removed -A, as it is
  semantically -a modified by -1.
- cleaned up message output a bit. still, the quiet variable should be
  used throughout the program. at best, create some generic output
  function, which obeys a global verbosity level variable.
- optimized + cleaned up configuration parser slightly
- minor cleanups

add an (almost) unique id to every uploaded message and search for it
right after. i thought about using the message-id, but a) it is not
guaranteed to be unique in a mailbox (imagine you edit a mail and store
the dupe in the same box) and b) some mails (e.g., postponed) don't even
have one. a downside of the current implementation is, that this
id-header remains in the mailbox, but given that it wastes only 27 bytes
per mail and removing it would mean several roundtrips more, this seems
acceptable.
i changed the line-counting loop to use a mmapped file instead of
reading it in chunks, as it makes things simpler and is probably even
faster for big mails.
the amount of goto statements in my code may be scary, but c is simply
lacking a multi-level break statement. :)

this is the "shut up" patch. :) it makes the -q option consequent, so to
say.
additionally it adds an -l option which gathers all defined/found
mailboxes and just outputs the list. don't ask what i need it for. ;)

.SH DESCRIPTION

mailbox with a remote IMAP4 mailbox, suitable for use in IMAP-disconnected
mode. Multiple copies of the remote IMAP4 mailbox can be maintained, and
all flags are synchronized.

By default, the configuration is read from ~/.isyncrc if it exists.
.TP
\fB-1\fR, \fB--one-to-one\fR
Instead of using the mailbox specifications in ~/.isyncrc, isync will pick up
all mailboxes from the local directory and remote folder and map them 1:1
onto each other according to their names.
.TP
\fB-I\fR, \fB--inbox\fR \fImailbox\fR
Exception to the 1:1 mapping created by -1: the special IMAP mailbox \fIINBOX\fR

When synchronizing multiple mailboxes on the same IMAP server, it is not
