Subject: Add _bin/get_mail.sh for better handle of email fetch

Since ``offlineimap`` sometimes just gets stuck, which blocks new
instance from running, this little script is composed to better
handle this stuck by first force kill existing instance.

However, this script in current state cannot work well with ``mu4e``.
