Templates/Listviews

* removed most templates by sensibly restructuring lvTab-data. Util::toJSON() does the rest.
 * taught Util::toJSON() to recognize values prefixed with $ as js-code
 * use Util::toJSON whenever possible
 * misc
   - mail attachments are displyed again
   - always show all currency rewards on Quest-LVs
   - suppress an error, when encountering unused ItemMods
