Bug 5231 Add search for field read and write references
The UI should support the following new JDT Core feature: Search for field read and field write references. Two new constants have been added on IJavaSearchConstants to be used when creating a field reference search pattern: - READ_REFERENCES: the search results contain *only* read access to a field. - WRITE_REFERENCES: the search results contain *only* write access to a field. If REFERENCES is used, then search results contain both read and write accesss to a field.

		result.setLayout(layout);
		fLimitTo= new Button[fLimitToText.length];
		for (int i= 0; i < fLimitToText.length; i++) {
			Button button= new Button(result, SWT.RADIO);
			button.setText(fLimitToText[i]);
			fLimitTo[i]= button;
