Subject: [PATCH] [MJAVADOC-723] Upgrade Maven Reporting API to 3.1.1/Complete
 with Maven Reporting Impl 3.2.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This not only upgrades to Maven Reporting API 3.1.1, but also logically
completes this plugin with bits from Maven Reporting Impl 3.2.0 because
we cannot inherit from AbstractMavenReport since Java does not support
multiple inheritance. It should now behave as if using m-r-impl.

This closes #158
