Sometimes fluxbox is used as a component of a desktop environment ( e.g., the "Lumina Desktop"). It's easier and more stable for this kind of "users" to disable the toolbar or the slit alltogether. Why not configure these features out? Because then they would need 2 installations of fluxbox: One without the slit and the toolbar (and perhaps other components) and one with them. This implements feature request #314, at least partially. This commit also looks bigger than it actually is: I refactored and cleaned up classes Fluxbox and BScreen.
