[ZF-936]: Added getScriptPath($name), getHelperPath($name),     getFilterPath($name), getHelper($name), getFilter($name), and getFilters()     methods. Notes:     * getHelper() and getFilter() will instantiate the filter of $name if not       already instantiated     * getHelpers() and getFilters() only return already instantiated helpers and       filters; i.e., they won't return all helpers and filters available     * getHelperPath() and getFilterPath() will instantiate the associated helper       or filter in the process of discovering the path, if not already       instantiated     * Tests to come
