[FEATURE] Additional params for HtmlParser attribute userFunc

Sub parameters passed to the HtmlParser tag configuration like:

fixAttrib.[attribute].userFunc.myparam = test1

will be passed to the configured user function in an array. The
attribute value will be stored in the attributeValue array key.

To keep backward compatibility the attribute value will be passed as
string to the user function when no additional attributes exist.
