Improve the way TextEditor field contents are displayed in detail page

[javiereguiluz]

TextEditor field creates HTML content because it allows to use paragraphs, bold text, links, etc.

In detail page, we display the escaped HTML contents for security reasons. But, in many cases, you want to display the rendered HTML contents. This is fine because contents were created by employees, not end users.

Also, we should add an option to display the full contents without an scroll bar. By default, we set a max-height to not break the page design when the content is very long.
