Opened up the upper bound for Spring to be able to work with Spring 4. Expanded lower boundary of Slf4j dependency to 1.6.4 to let STS 3.x work with the JAR out of the box.
Extracted methods taking a Specification from JpaRepository into JpaSpecificationExecutor. Introduced QueryDslPredicateExecutor that takes QueryDsl Predicate objects to execute them. Introduced QueryDsl specific subclass to execute Predicate instances. Extended JpaRepositoryFactory to rather use the QueryDsl specific implementation if the actual user repository implements QueryDslPredicateExecutor. Added test case to ensure detection of query class. Added QueryDslRepositorySupport to ease implementation of repositories. Added constructor to QueryDslJpaRepository to take an EntityPathResolver to allow plugging in a different implementation. Extracted actual EntityPath resolution tests into unit test for SimpleEntityPathResolver. Check for QueryDsl classpath presence to prevent ClassNotFoundExceptions.
