Feature request: minimize/close to system tray

[igormp]

Hello there! Just started using vikunja and have been loving it so far! :)

Would it be possible to add an option on the desktop app to minimize/close to tray?

Not sure how doable/hard it'd be since I see that the desktop app is just a wrapper over the regular web front-end. I know that Electron does offer this possibility without much issues, but I have no idea how this could be done since it'd be a desktop-specific config.

If it's just a matter of just editing the desktop/main.js file, maybe I could try it myself and create a PR later.
