Feature: #59712 - Additional params for HTMLparser userFunc

See forge#59712


It is now possible to supply additional parameters to a userFunc of the HTMLparser:

myobj = TEXT
myobj.value = <a href="/" class="myclass">MyText</a>
myobj.HTMLparser.tags.a.fixAttrib.class {
	userFunc = Tx\MyExt\Myclass->htmlUserFunc
	userFunc.myparam = test1

By default only the value of the processed attribute is passed to the userFunc as the first parameter:

function htmlUserFunc($attributeValue, HtmlParser $htmlParser) {
	// $attributeValue is set to the current attribute value "myclass"

When additional options are provided as described above, these options will be passed in the first function parameter as an array. The attribute value is passed in the array with the attributeValue array key.

function htmlUserFunc(array $params, HtmlParser $htmlParser) {
	// $params['attributeValue'] contains the current attribute value "myclass".
	// $params['myparam'] is set to "test" in the current example.



If additional parameters are provided to the HTMLparser userFunc setting the first parameter passed to the called function changes from a string with the attribute value to an array containing the attributeValue key and all additional settings.

This has an impact to all installations where additional parameters are used in the userFunc setting of the HTMLparser.
