v0.1.2

• Fix: Allow negative values in --location and --scheme arguments (#1)

• Fix: Apply gamma ramps without checking if it's changed in daemon mode
  to restore the desired ramps faster when an external program changes them. See
  'Why does the redness effect occasionally switch off for a few seconds?' in
  docs/redshift-readme.md

• Fix: Minor changes to the set command

  • Remove the hard requirement of providing at least one of the temperature,
    gamma or brightness cli arguments
  • Always use the default values of temperature, gamma and brightness when they
    don't exist. Don't use the values provided by the config file

• Feat: Add systemd service

• Windows support is experimental and provided for testing purposes
