Release Red Solitude v2.2.1

🚀 I'm happy to announce the release of my first theme "Red Solitude".

I've used this theme for my self for quite a while, which is why I am starting with v2.2.1 😅

It is a dark theme with a strong accent color and a 3D look. It has some extra features and is configurable via the Style Settings plugin.

Use the Style Settings plugin to enable the below mentioned features .

• Custom workspace background
• Translucent panels
• Active line effect
• Hover over line effect

Feel free to open an issue, if you find any bugs or have recommendations on what I could add to the theme.
