Feature: #104220 - Make parseFunc allowTags and denyTags optional 

Description 

Defining the TypoScript properties allowTags or denyTags for the HTML processing via stdWrap.parseFunc is now optional.

Besides that, it is now possible to use allowTags = *.

Impact 

By omitting allowTags or denyTags, the corresponding rendering instructions can be simplified. Security aspects are considered automatically by the HTML sanitizer, unless htmlSanitize is disabled explicitly.

10.value = <p><em>Example</em> <u>underlined</u> text</p>
10.parseFunc = 1
10.parseFunc {
  allowTags = *
  denyTags = u
}
