General fixes

+Fixed a bug that didn't delete artifacts when a player deleted his
account
+Added "(artifact)" if a village has an artifact in the village overview
+Added the artifact section in the multihunter panel (return to natars
doesn't work yet)

NOTE: To play this version of the game, you have to run this query first
(where "s1_" is the prefix of your server):

ALTER TABLE `s1_artefacts` ADD `del` TINYINT(1) NULL DEFAULT '0' AFTER
`lastupdate`;
ALTER TABLE `testtravian`.`s1_artefacts` ADD INDEX
`active-owner-conquered-del` (`active`, `owner`, `conquered`, `del`);
