removing smarty - part XIII (almost there)

- reimplemented Utilities-Page and Account-Page
- moved account-ajax to ajaxHandler
- AjaxHandler::handle() can no longer call itself, if the parameter is empty
- cache is now compressed (has a negligible delay)
- revisited User-Class / Accounts:
 * implemented mail-confirmation (be sure to configure your server appropriately)
 * implemented recovery of password or username
 * there are now 3 options to auth against: 1) aowow-DB (default); 2)
   wow-auth-DB; 3) user-defined script (SOAP or similar exotic methods)
 * dropped the aowow-cookie, it relies on php-sessions now
 * reworked how bans are handled (can now also ban from upload, rate, comment)
- fixed enhancements on itemTooltips

account related localization for FR, ES and RU is lacking (help is appreciated)
_account and _account_banned have changed and are incompatible with the prvious version
