The button widget, implemented in the Uize.Widget.Button class, has been modified to give the active display state precedence over the grayed display state.

This means that if a button is selected (such as with a checkbox style button), then it will always be evident that the button is selected - even if the button becomes disabled. A checkbox style button could be disabled to prevent its selected state from being modified. Previously, if a checkbox style button was both selected and disabled, then it would only appear disabled (i.e. it would appear unchecked, thereby falsely reflecting its value).
