zfs_uploader 0.6.0

Changed

• Add max_incremental_backups_per_full config option. Setting the option
  allows for multiple full backups. Do not set option for one full backup
  and one or more incremental backups. #29

• Replace max_incremental_backups config option with max_backups, to
  avoid having to set a limit for incremental and full backups. Full
  backups are only removed when there are no dependent incremental backups.

Fixed

• Remove misfire_grace_time so that jobs always run if they are late. #49
