What was designed as a new feature appeared as a regression: users were
not able to choose a bootstrap gray as a background color anymore but
instead got the possibiility to choose a hardcoded gray. This commit
restores the use of the custom gray palette that themes can customize
and which automatically uses the correct text color when used as a
background. This also allows to remove ugly inline style from snippet
definitions and allows to solve bugs like the described below one:
---------------------------------------
Also add bg-* classes on snippet cards:
---------------------------------------
Snippet cards are often put (or may be put by the user) in an element
which have a bg-* class on it. This means that the card will still have
a white background (as chosen by BS4 by default) but the text color will
be adapted to that ancestor bg-* classed element.
This commit forces the card background color (as suggested by BS4) with
bg-* classes.
