promote checkstyle to a default report

checkstyle will run with the AddThis style on all builds, indivdual
projects will no longer need copy and paste.

Note: The least annoying thing to do seems to be to link to the
checkstyle file in master.  It changes rarely and linking to a tag is
a pain when developing new versions.  This does mean that changes in
master can affect the outcome of tagged downstream builds in a minor
way.
de-dupe findbugs config in the reporting section

This also fixes skipping findbugs, since that property appears to be
in the reporting section to matter.
fine grained skipping of findbugs & jacoco
enable Apache Rat plugin

Note: Because the excludes property is an xml structure and not just a
string it can't be exposed as a simple text property.  Downstream poms
that need to override will have to reference the full plugin.
