RAT-204: Unify resource handling.
* Module: apache-rat-core
** Use IOUtils.closeQuietly() instead of manual try/finally/if !null - Java7 tryWithResources would ease that even more!
** ClaimAggregator: remove unnecessary (un)boxing of integers.
** DirectoryWalker: Avoid possible null access during comparison if files array is null.
** Inline variables that are initialized just before being returned.
** Refactor test class members to be private
** Remove redundant javadoc elements that are IntelliJ-autogenerated.
