ZF-3172: Fluid interface not provided consistently by filters


Some filters do not provide a fluent interface for their setter methods. Sometimes there is inconsistency even in the same filter:

Zend_Filter_HtmlEntities::setCharset() provides a fluent interface Zend_Filter_HtmlEntities::setQuoteStyle() doesn't provide a fluent interface


Please evaluate and fix/categorize as necessary. Can we do this as a backwards compatible fix?

Fixed in svn r11783
