Work around Google marking fetched messages as read about imap2maildir

[blocke]

When attempting to use imap2maildir for the first time on a gmail account with over 3,000 messages with the default "SEEN" criteria only about 200 or so emails were pulled down. Specifying the "OLD" criteria allowed imap2maildir to see the full mailbox. This might be related to the fact the bulk of the 3,000 messages were pulled over from another gmail account via gmail's builtin pop import mechanism and those emails might be tagged differently somehow.

Just an FYI.

I believe a fetch (BODY.PEEK[]) instead of (RFC822) will do the trick.. Another thing we might want to add for each select(folder) is select(folder, readonly=True) which will execute "EXAMINE" instead of "SELECT" which is basically read/write mode.

Would you like a patch for these changes?
