Add tab group name on the title

[ooker777]

It's the same with the Panorama Tab Group Name addon. With this feature, you can:

• Know what tab group you're in (move the tab bar to the side will reveal the window title permanently). So if I know that I'm on the Work tab group, I won't open Facebook.
• Track time spent on each tab group, with a help of other time tracking software. This will solve issue https://github.com/Quicksaver/Tab-Groups/issues/422
