Spark ComboBox vs DropDownList

I discovered yesterday that with the new Spark components there was no "editable" property on the ComboBox component.

I realized that the Spark ComboBox is always editable by default, and with no way to turn that off I was confused. Did a little research and found that to have what would have been ComboBox editable="false" in Halo is now simply DropDownList. Two different components.

I think it makes sense to have these separate.
