modified the command line password of the mysqldump command to enclose the password in quotations so that special characters do not cause the command to fail (and the connection to mysql to be rejected).
fixed type-o in error which specified the incorrect s3 configuration file (s3config instead of s3_config)
fixed command line spec for change in how password is specified in command line
modified configuration to allow gzip compression to be specified, defaults to previous value of 9
modified configuration to allow you to specify custom mysqldump commands
