Add a MVC portlet that will enable to use soy templates instead of JSP similar to the FreeMarker extension.
Things that need to be done:
Create SoyPortlet extension of MVCPortlet - will be responsible for scanning of the soy template folder and loading the resources.
Update TemplateResourceLoadreUtil to be able to process also lists of resources.
Create SoyTemplateResourceLoader - responsible for the actual resource loading.
Create an example portlet to demonstrate the usage.
