ZF-11132: Zend_ProgressBar_Adapter: Finish method allow paramater

Description

Hello,

the abstract method "finish" in Zend_ProgressBar_Adapter does not allow a parameter, f.x. to set the text.

I need to translate the finish text, so i need to set the translated text in php and not in javascript.

-> Add an optional paramter to the finish method.

See file patch.

Allow to define an array as paramter (optional).

Should be compatibel with the current implementation.
