After moving to the new react:component taglib, there is more java logic that we can extract out of the JSP and into a DisplayContext.

For example instead of:

		<%
		Map<String, Object> data = new HashMap<>();

		data.put("formName", renderResponse.getNamespace() + "synonymSetsForm");
		data.put("inputName", renderResponse.getNamespace() + "newSynonymSet");
		data.put("originalInputName", renderResponse.getNamespace() + "originalSynonymSet");
		data.put("synonymSets", synonymSets);
		%>

		<react:component
			data="<%= data %>"
			module="js/SynonymSetsApp.es"
		/>

We can have:

		<react:component
			data="<%= editSynonymSetDisplayContext.getData() %>"
			module="js/SynonymSetsApp.es"
		/>
