Added support to missing Symbian ambient light levels
Added support to missing Symbian ambient light levels

Added support to missing Symbian ambient light levels KAmbientLightCloudy
and KAmbientLightCloudySunny by changing switch/case to separate if
clauses. By adding support this way we do not need to use new Symbian
side enums in QtMobility code, so code should work also in case that
those new enums are not defined in some Symbian platform where this same
QtMobility code is used.
