Adapted JPA 2.1 example to latest changes in Spring Data JPA.

Changed method to derive the stored procedure metadata to be named after the stored procedure so that the name doesn't have to be customized on the annotation.

Switched to Spring Data JPA master branch artifact as the stored procedure support has been merged recently.

 Calling `UserRepository.plus1BackedByOtherNamedStoredProcedure(…)` will execute the stored procedure `plus1inout` using the meta-data declared on the `User` domain class.
 
-`UserRepository.derivedStoredProcedureDeclaration(…)` will use the stored procedure name declared in the annotation and default to positional parameter binding and expect a single output parameter of the backing stored procedure.
+`UserRepository.plus1inout(…)` will derive stored procedure metadata from the repository and default to positional parameter binding and expect a single output parameter of the backing stored procedure.
