Subject: [PATCH] #593 - Improve declaration of Javadoc plugin to avoid
 failures on older Maven versions.

Older Maven versions (tested on 3.0.3) seem to reject the shorthand notation we use in the <additionalJOptions /> element of the Javadoc plugin declaration. More recent ones automatically interpolate a single textual element contained in the element, while older ones require the usage of a nested <additionalJOption /> even for single values. We now use the more explicit variant.

Related tickets: #591.
