[qutebrowser] Set webpage bg to grey

Defaults webpage backgrounds to 'davy grey'. Generally, this will be
overwritten in the stylesheet that is automatically applied through
styler. Setting the background color to a dark one does however prevent
the blinding whiteness when first opening a new page in a dark room and
it still has to load (as well as when rapidly switching between tabs).
