Added

• Add !env chain source, for loading environment variables
  • This is intended to replace the existing {{env.VARIABLE}} syntax, which is now deprecated and will be removed in the future

Changed

• "Edit Collection" action now uses the editor set in $VISUAL/$EDITOR instead of whatever editor you have set as default for .yaml/.yml files #262
  • In most cases this means you'll now get vim instead of VSCode or another GUI editor
  • Closing the editor will return you to Slumber, meaning you can stay in the terminal the entire time

Fixed

• Environment variables in {{env.VARIABLE}} templates are now loaded as strings according to the OS encoding, as opposed to always being decoded as UTF-8
