Bug 198201 [DataBinding] Provide POJO observables
There have been quite a few requests on the newsgroup recently about trying to use POJOs and filling up logs with error messages about not being able to register property change event listeners. It would be nice to provide a cleaner solution than using the JavaBean support that we provide today.

	public JavaBeanObservableMap(IObservableSet domain,
			PropertyDescriptor propertyDescriptor) {
		super(domain);
		
		this.propertyDescriptor = propertyDescriptor;
		this.listenerSupport = new ListenerSupport(elementListener,
				propertyDescriptor.getName());
		init();
	}
	protected void hookListener(Object domainElement) {
		listenerSupport.hookListener(domainElement);
	}
	protected void unhookListener(Object domainElement) {
		listenerSupport.unhookListener(domainElement);
	}
	protected Object doGet(Object key) {
		try {
			Method readMethod = propertyDescriptor.getReadMethod();
			if (!readMethod.isAccessible()) {
				readMethod.setAccessible(true);
			}
			return readMethod.invoke(key, new Object[0]);
		} catch (Exception e) {
			Policy.getLog().log(
					new Status(IStatus.ERROR, Policy.JFACE_DATABINDING,
							IStatus.ERROR, "cannot get value", e)); 
			throw new RuntimeException(e);
