Add support for projections using repository query methods

[eiswind]

When I create a Repository like:

interface TRepository : Repository<T, ID> {
    fun findAll(page:Pageable) : List<T>
}

the implementation uses

 Page<T> JdbcAggregateTemplate.findAll(Class<T> domainType, Pageable pageable) 

under the hood, which issues an (in this case) unnecessary "select count".

Can you think of adding an implementation that omits the additional select?
