Remove usage of {{{ }}} in the html report

[ebidel]

In some places we use {{{}}} to render our own data (example). Those are fine.

However, we should remove {{{ }}} in places where we render user data (example]. Those are there to render code snippets and links in helpText and audit descriptions. Instead, we should create Handlebar helpers to render links and code snippets.

This works today if it appears in json loaded into the app:

"helpText": "<img src=\"test.gif\" onerror=\"alert('oops')\"> Text..."
