Drop unneeded parameters to the ScreenManager constructor

All calls to ScreenManager_new always pass the same first
five values, the orientation is always HORIZONTAL and the
y1 parameter is always the height of the passed-in header
struct pointer.  I think its safe to assert at this point
that no VERTICAL orientation will arrive (if it does, its
no harm in re-adding this then) - so we can remove unused
conditionals (and TODOs) based on orientation too.
