Implement automatic colorisation settings
As described in this libretro blog post, the Gambatte core is now able to "automagically select the ‘best’ (most colourful/appropriate) palette for each game, using an internal database". Should we make Games do the same? In that case, we could perhaps add a way for the user to switch between "original" monochrome and "colorised" views.
