Improve Algorithms for Resource Validation and Template Localization

                 Key: JS2-739
                 URL: https://issues.apache.org/jira/browse/JS2-739
             Project: Jetspeed 2
          Issue Type: Improvement
          Components: Decorations/Themes
    Affects Versions: 2.1.1
            Reporter: David Sean Taylor
            Assignee: David Sean Taylor
             Fix For: 2.1.1

During load testing, we discovered the Decoration valve was calling code in the BaseDecorator
that inefficiently made calls to validate resources, combined with applying a seldom used
mediatype/language/countrycode fallback algorithm. This effort will optimize these inefficiencies
with caching and optionalizing the fallback algorithm and resource validation. The overall
expense of the existing algorithm was leading to as much as 18-24% CPU usage per request.
Additionally, there are other calls made to locating templates like from velocity templates,
where we may gain some more performance improvement.
