removing smarty - part XIV (only one more..)

- added some forgotten account-srings
- fixed an error handling ItemFilter /w upgradeItems + markdown appearing in tooltips
- relaxed session-regeneration (only regenerates on status changes (signin/-out)), fixes losing the session, when opening multiple tabs at once
- striped smarty from profiler (only cleanups remaining)
- moved profiler-ajax to AjaxHandler
- created a (dummy, for now) ProfileClass to handle Chars and Profiles
