Introduce set default button when attribute is set

Set a default value using the "defaultColorValue" settings namespace
attribute. The general idea is often we want set a value of say "-1"
and let framework handle it. One such scenario would be if you are
changing the color of a ImageView using ColorFilter. When framework
receives a "-1" value, framework sets the ImageView ColorFilter to null,
restoring the ImageView to original state.
