ZF-2820: Zend_Controller_Router_Route_Regex missing protected $_map

Description

In the constructor $this->_map = (array)$map; is used, but $_map is never declared, so by default it's added as a public property to the class.

It works, but it should be declared protected because it's never accessed from the outside anyway.

Comments

Fixed for next minor release with SVN r8933.
