Fabian Boehm f116a81250 Make default theme use named colors only
This gives us the biggest chance that these are *visible* in the
terminal, which allows people to choose something nicer.

It changes two colors - the autosuggestion and the pager
description (i.e. the completion descriptions in the pager).

In a bunch of terminals I've tested these are pretty similar - for the
most part brblack for the suggestions is a bit brighter than 555, and
yellow for the descriptions is less blue
than the original.

We could also make the descriptions brblack, but that's for later.

Technically we are a bit naughty in having a few foreground and
background pairs that might not be visible,
but there's nothing we can do if someone makes white invisible on brblack.

Fixes #9913
Fixes #3443
