sw: remove char color GrabBag and fix export, fix tint/shade calc.

Don't store values from grab bag when exporting character theme
colors and tint/shade values. The values could be wrong now and
aren't needed anyway as we support the values in the model.
Add proper export support for char color theme information with
correct conversion of values into tint/shade values in 0-255
inverted interval.
This also fixes the import of tint/shade values whcih calculation
was slightly off. We divided by 256 instead of 255, which
introduced an error.

In addition introduce ThemeColorUsage enum, which marks if the
theme color type has a specific "usage" - text or background. This
is determined on import if the theme type is background{1,2} or
text{1,2}. This is then taken into account on export, so the
exact type is preserved.
