[ANN] New gtk client, with colors

[Ecmel B. Canlier]

Tested it for a little bit and it seems really nice! The "user
experience" is definitely very close to what I imagined for Moonlander.

> The browser will have a different color for each domain you visit.

On dark GTK themes (specifically Arc-Dark in my case), the top UI color
on some pages look _very_ light and makes the important parts of the UI
hard to see¹.

One suggestion would be to add a "dark mode" switch that tones down the
brightness of the generated colors. You might also want to add an option
to turn the coloring off entirely for people who want all their programs
to share the same look.

My slow internet will thank you for this one :)
 
> It works. Until I find another bug

Here's one: Some quote lines are not parsed correctly².

Lastly, if you want more stuff to do: a way to configure how the pages
are rendered would be a nice addition. As currently the text is too
small, and the lines go for too long without wrapping. Being able to set
the maximum line width (bonus points for centering), and font
configuration (preferably different for each line type) would be pretty
neat. Color customization would be neat too, but that's not as
important as being able to read things.

I might take a shot at implementing the customization stuff, but don't
count on me :p
