FYI: contributed JpaUserDetailsService & JpaUserDetailsManager

Hi all,

Since I figured someone might want to use JPA as their implementation of UserDetailsService and/or UserDetailsManager, I contributed two classes, JpaUserDetailsService and JpaUserDetailsManager, that do the boilerplate work of the implementation, leaving the meat to subclasses.

The source files are attached to the issue

https://jira.springsource.org/browse/SEC-1737

Maybe they'll get included in a contrib module some time. In the meantime, you can use them for yourselves.

Enjoy,
Matthew
