ZF-6408: Let Zend_Filter_File_Rename accept filename only as target

Description

Let Zend_Filter_File_Rename accept filename only as target:


$filter = Zend_Filter_File_Rename('filename.ext');

The full path should be gathered from the dirname(source).

I'm not sure if its a BC, because at the moments this would be handled as a relative path (like ./filename.text)
