style(web/tvl/logo): Add dark & light versions, dim background r/2917

Currently the pitch black colour of the logo outline looks a bit
strange on the homepage, dimming this to the same colour as the text
is nicer.

While poking around in that colouring segment I also made a way to
spit out light logos instead (to use on dark backgrounds).

Note: The light colours are just picked from our web CSS, but they
don't actually look good yet - it also needs a different palette. For
now nothing uses the light version.
