* Fix bug where config is not referenced properly when script is called from another directory (https://github.com/ameir/mysqlbackup/issues/1)
updated README.changed to use config file under the script directory. added mysql socket option
show the email addresses which the script has been mailed to to let we know what it is doing.
changed MUA full path.This must be set manually because of the PATH env var changes when executed by cron daemon.
added mysql and mysqldump command full path.
