Automatic dark/light themes

This Cinnamon applet brings the ability to automatically switch between dark and light themes and desktop background at twilight times based on a location.

Features

• Dump system themes and desktop background settings as light/dark presets in one click in order to keep using the Cinnamon settings menu.
• Sync location from the system Region and City settings using a local database to automatically determine the geographical coordinates.
• Enter manually any geographical coordinates if needed.
• Always sync instantaneously with external changes of color scheme, region/city and time (useful in e.g. after a sleep wake up).
• Fully event and scheduling based, zero polling.
• Automatic mode switch can be disabled.
• Dark/light mode can always be switched manually.
• Schedule any amount of commands to launch at twilight times.
