[FEATURE]: Option for monochrome system tray icon

[ksinar]

Summary

Currently, the system tray icon is colorful. It would be nice to have an option for a monochrome/white system tray icon as well.

A clear and concise description of what you want to happen

My intention is not to hide it, but have an option to use a monochrome color scheme for the icon so that it matches other breeze system tray icons. Here is how it looks like on my panel: https://i.imgur.com/GzZRZ4t.png

The new tray applet will use monochrome icon by default. For more information, see #23.
