css: remove repeated property
'margin' property was repeated for the same selector
css: fixed font-family
There is no 'sans' font-family, replaced with 'sans-serif'
color: set _colormode to None when mode is unset (
issue3895)
Previously, colorui assumed that it would only be called when mode wasn't
None.
7ae12ce87594 changed that, so now colorui needs to care about whether it
should colorize output.
color: turn colorui functions into forwards when color is None
colorui will be set to None as necessary in an upcoming patch.
