Bug: generated ArgumentTypes end with a double ..

When the argument types are rendered to be included in the site argument_types.txt is written.

This file (in both variants in apache-rat-plugin and apache-rat-tasks) contains a double full stop as a full stop seems to be rendered after the last entry.

Thus the generated webpage ends with:

{{<StyleSheet>
Either an external xsl file or one of the internal named sheets. Internal sheets are:
plain-rat: The default style.

missing-headers: Produces a report of files that are missing headers.

unapproved-licenses: Produces a report of the files with unapproved licenses.

xml: Produces output in pretty-printed XML..}}

instead of

{{<StyleSheet>

missing-headers: Produces a report of files that are missing headers.

unapproved-licenses: Produces a report of the files with unapproved licenses.

Test assertions in HelpTest  indicate that the output contains two dots.
