v3.2-beta1

New in v3.2 so far:

• --help output is split up in nice sections now.
• Moved documentation to wiki and split it up.
• Created zfs-check, a tool to generate checksum streams of zfs datasets, to compare datasets with eachother. (Will be used in conjuction with zfs-autoverify)
• Started working on an zfs-autoverify tool to actually verify your backups. (this took some refactorring and extracting common code to a ZfsAuto baseclass) Still work in progress.
• Allow non-recursive selection of datasets by setting autobackup:name=parent. (usefull for /var/lib/docker)
