Light Circuit for TST od shr1k

I'm a weirdo who uses a dark theme for everything on my system, except the browser.

Some examples of how it plays nice:

Tree Style Tab: A nice (IMHO) background image that doesn't get mangled by vertical tabs.

TST Colored Tabs: Sensible colour scheme that doesn't clash horribly with the extension's default colours.

System dark theme: Doesn't contrast too strongly against a dark theme (tested with Arc Dark and Materia Dark on Linux/KDE)
