Add paragraphs with fieldset

[jauco]

Allow the user to define a paragraph template that can then be used in the document. The template contains the dictionary enumeration and lets the user pre-fill the labels. Each time a paragraph is constructed based on the template the fields are copied over to the paragraph and the user can fill in the body texts. The user is also able to append new labels. Removing labels from the template will leave them in the paragraphs based on the template.
