zf1-future: Broken Zend_Db_Table_Rowset::current function

Hello,

First of all: thank’s a lot to maintain ZF-1. Great work! 😃

Am I wrong? I think the return type of Zend_Db_Table_Rowset::current function recently added mixed is wrong. The function return Zend_Db_Table_Row_Abstract or null. mixed is union of string|int|float|bool|null|array|object|callable|resource. So Php complain when the function return Zend_Db_Table_Row_Abstract.

Here’s the hash of the commit: ad81d0c2c6b5ee9207627022197b3a952418256b
