                        PlutoFactoryFactoryBean.java
                        ServletConfigFactoryBean.java
  Log:
  Two new Spring FacgtoryBeans:
  PlutoFactoryFactoryBean helps assemble Pluto factories.
  ServletConfigFactoryBean allows us to "slip" a ServletConfig into Spring via static when we create the Engine.
