WP_Date_Query missing column user_registered

[ChriCo]

In WP_Date_Query-Class theres a missing column "user_registered" and no support for it in WP_User_Query.

We've to add the missing Column in WP_Date_Query-Class on Method validate_column and add the query_var on WP_User-Query-Class.

Added patch with unit-tests

I like where this is going

I uploaded a cleaned up patch. Looking at the tests, though, it doesn't look like there are any functional assertions here. It's simply comparing that the SQL output of a WP_Date_Query instance is returning the same WHERE as the WP_Date_Query instance inside WP_User_Query. That's insufficient as they could all be returning nothing and the whole thing would pass.

We need to essentially borrow Tests_Comment_DateQuery or Tests_Query_DateQuery and make our own Tests_User_DateQuery in tests/phpunit/user/datequery.php.

Moving out of 4.0, though this is simple enough we can bring it back in if tests are written.
