2. BUG FIX: Uize.Node.setValue and myWidget.setNodeValue

An IE-specific bug was found with the Uize.Node.setValue static method, which also affected the setNodeValue instance method of the Uize.Widget class.

A workaround was put in place for an issue in IE where document.getElementById will return a node that has the specified id value set for its name attribute but not its id attribute. The IE issue resulted in the two methods not working correctly for radio buttons. It is now fixed.

3. MyClass.get () and myInstance.get ()

When no parameter is specified when calling either the MyClass.get static method or the myInstance.get instance method, then all the static or instance values, respectively, for the declared state properties will be returned.

4. Uize.Widget - Changes to busy/enabled Mechanism

The myWidget.isBusy instance method has been KILLED in favor of the busyInherited state property. Similarly, the myWidget.isEnabled instance method has been KILLED in favor of the enabledInherited state property. The barely used myWidget.checkInherited instance method that was technically public but never used outside of the Uize.Widget base class has been KILLED.

The new interface is more in keeping with the state interface philosophy of the UIZE JavaScript Framework, and also allows us to leverage the event system to watch on changes in the busy and enabled states by using the 'Changed.busyInherited' and 'Changed.enabledInherited' instance events. Additionally, the new state properties are more semantically correct. It was always confusing that isBusy returned a boolean, while the busy state property could have the string value of 'inherit'.

myWidget.isBusy ()     >> BECOMES >>  myWidget.get ('busyInherited')
myWidget.isEnabled ()  >> BECOMES >>  myWidget.get ('enabledInherited')

It's a little more to type in the cases where this functionality is used, but it's fewer methods for every widget instance.
