Cannot add window frame and divider to skylights

[asparke2]

OpenStudio currently limits the attachment of WindowPropertyFrameAndDivider objects to FixedWindow, OperableWindow, and GlassDoor SubSurfaces. This may have been a limitation of EnergyPlus at some point, but does not appear to be one now. The DOE prototype buildings use frames on skylights, which the current implementation prevents.

Solution:
Extend the list of acceptable SubSurface types to include Skylight. Perhaps it should also include other types as well?

I suppose it is important to make sure the the Forward Translator code for this field will work on skylights (I think it will).
