Support returning the correct values for the different QuerySet methods when using .values() and .values_list(). (#33)
* Support returning the correct values for the different QuerySet methods when using .values() and .values_list(). * Fix slicing on QuerySet. Fix django queries test, and remove some ignored errors that are no longer needed. * Remove accidental change in RawQuerySet. * Readded some still-necessary ignores to aggregation django test. * Add more tests of first/last/earliest/last/__getitem__, per mkurnikov's comments. - Fix .iterator() * Re-add Iterator as base-class of QuerySet. * Make QuerySet a Collection. * - Fix return type for QuerySet.select_for_update(). - Use correct return type for QuerySet.dates() / QuerySet.datetimes(). - Use correct type params in return type for QuerySet.__and__ / QuerySet.__or__ - Re-add Sized as base class for QuerySet. - Add test of .all() for all _Row types. - Add test of .get() for all _Row types. - Remove some redundant QuerySet method tests. * Automatically fill in second type parameter for QuerySet. ... if second parameter is omitted.
