Enable markdown renderer for more than just help texts

[triole]

The goal of this pull request is to have the markdown renderer available for question texts as it is right now for help texts.

Description

• enable markdown rendering for the following elements in questions answer section
  • page titles
  • question set titles
  • question texts

Related issue: #441

Motivation and Context

The STAMP project needs it because they love to style their text snippets.

Remarks

There are titles which are bold by default. I did not want to have those and removed them using css.

.form_label {
    font-weight: unset;
}

My fix..

How has this been tested?

does this also have to do with adding (markdown) links to the text of options for example?

[triole]

Currently not. This is something that will probably be added in the future. Every change should mentioned above in the description. What is not in the description is not in the code.

[MyPyDavid]

I could add some parts for that if it will make this PR ready for the next release.
Is there still much to be done for this PR? It's not clear to me.

When I would add this for the option text, I could simply use your changes and apply them to the options right?

[jochenklar]

The markdown support for option text and help are implemeted in the interview branch. Since I want to implement markdown in catalog/section/page/questionset titles and question texts there as well I can add the corresponding code in the non angular parts already here.
