No helper to strip Html Tags from Content String

In certain scenarios it can be beneficial SEO to link internally via product descriptions. Given that the product descriptions are also used to generate the .json for structured data it might happen that the description breaks the .json.

Same goes for any field users can input html.

And all fields should be made json safe. i.e. encode quotes. This can be tricky as the last time I used {{{json property}}} it would return nothing if the property was blank, breaking the syntax.

Another less known issues is if the html includes a closing script tag. This breaks out of a script even if the text is inside a string.
