Dependabot

[Ralph Goers <ra...@dslextreme.com>]

If you are going to apply the PRs dependabot generates then you need to make sure the appropriate checks are done.  Dependabot upgraded the maven checkstyle plugin. This plugin is used in the mvn site build, but I believe our builds don’t normally run that so it looked like everything was ok. However, there were breaking changes in the checkstyle configuration so the site no longer builds on master. I tried making changes but it kept getting different errors with each one I would fix so I finally just reverted it back to the prior version. 

If someone wants to upgrade the checkstyle pluigin they can go through the effort of fixing the configuration. I just want a working site build.
