spring 4 migration

Hi Broadleaf Team

Do you have any plans about migration to spring 4?
I upgraded BroadleafCommerce to spring 4, spring security 3.2, servlet-api 3.0, hibernate-validator 5.1 and guava 16.0.1.
The missing part for now are hibernate upgrade to 4.2/4.3 and update all spring namespaces locations to 4.0.xsd.
