Extend the .dot() method to take EOQualifier, EOSortOrdering and NSAr…

…ray<EOSortOrdering> to be synonyms for the prefix() methods. This overloading of #dot() makes prefixing existing EOQualifiers, EOSortOrdering and ERXSortOrderings much more intuitive. For example, let's say Company has a complex array of EOSortOrderings that takes into account things like outstanding invoice amounts, days past due, etc that is expressed in a static field called Company.FINANCIAL_SORT. With the dot() method you could easily create a new array of EOSortOrderings for the Invoice entity by simply writing: Invoice.COMPANY.dot(Company.FINANCIAL_SORT).then(Invoice.DUE_DATE). This allows each Entity to know about it's own EOSortOrderings and you don't have to have EOSortOrderings duplicated in every class (or component) that needs to do a sort.
