Wraps the servlet context especially for freemarker taglib resolution. This will trick freemarker TaglibFactory class
to "see" all jars in classpath as if they were jars in /WEB-INF/lib.
On Windows systems the implementation of getResourcePaths will return absolute paths including the drive letter. When
freemarker then calls getResource and getResourceAsStream we must not call the wrapped servlet context because its
not a valid URL and it will fail with a MalformedURLException. See MAGNOLIA-5651.
