The idea is to remove as many dependencies as possible for low-level ScriptletFilteringEngine in order to make it easier to reuse the module outside uBO itself. The high-level derived class takes care of caching and injection of scriptlets into documents, which requires more knowledge about the environment in which scriptlets are to be used. Also improve scriptlet cache usage to minimize overhead of retrieving scriptlets.
