v2.1.2-rc1

This is a release candidate meant for testing purposes only.
Below is a short list of things that has been crossed off from the v2.1.2 release so far.

• Partitions should have more flexible file system options
• Create a helper function for getting credentials input
• Install dhcp client by default (or warn about not having a dhcp/static ip configured)
• Support an already installed system
• Add option to support time zones
• Multi boot support
• Improve selecting from large lists
• Profiles should be able to trigger additional (non default) kernel boot params
• BTRFS subvolumes to support tools like Snapper with rollbacks etc.

(More in-depth detail on all the changes will follow on the actual release day of v2.1.2, since some changes sneak in as bonus features).
