Subject: [PATCH] flavours: Call bemenu selection from wrapper function

If we call the listing and applying function directly we either select a
random colorscheme on *no* selection or we have to make use of either
xargs GNU functionality or something like moreutils ifne to only select
color schemes on selection.

Can additionally set a random theme (if selection is 'random') or a
random light theme (if selection is 'light').
