There were occasions where removing the backup drive would confuse luks and prevent re-mounting. This fixes the issue by attempting to luks close and open the drive before mounting, thereby correcting any issues where the drive would stick.
Add docs explaining how to use luks and btrfs on arch.
Add basic manjaro playbook that installs software, sets up swap, and sets some basic configuration.
Add hosts and ansible examples to README. It's not much, but it's a start.
