config: add tweak.box-drawing-solid-shades=yes|no

Browse source 
When enabled, shades are rendered as solid blocks, using a darker
variant of the current foreground color.

When disabled, shades are instead rendered in a checker box pattern,
using the foreground color unmodified.

Default is enabled.
