Installing Arch Linux with an encrypted btrfs root, with GPT and UEFI support

# Take note of this:
# - The first thing you need is to identify which disk you're going to use. For the purpose of this guide, it will be /dev/sdX
# Be VERY CAREFUL if you have more than one disk on your computer, and DOUBLE CAREFUL if one of them is the one with your backups
# - Since btrfs does not support swapfiles (yet), we'll create a swap partition. In this guide, it will NOT be encrypted
