Artifacts update and optimizations

+Added the "Artifacts" section in the Admin Panel, which contains two
options: return a deleted artifact to the Natars and create new
Artifacts, assigned to a specified player
+Return to Natars coded, in the village section of the Admin Panel
+Moved a lot of functions and costants from Automation.php to the "new"
class Artifacts.php
+Optimized a lot the whole Natars creation process, decreased the number
of query of about 600
+Optimized a lot the function which deletes a player's account, it's now
executed almost instantly, even with players with a lot of villages
+Redesigned the map spawn system, using a more Travian-like village
distribution
+Fixed a bug that did show a broken village in the artifact chronology,
if that village was destroyed
+Reduced the amount of redundant code (about 230 lines) for
27_1.tpl/27_2.tpl and 27_3.tpl
+Fixed a bug that permitted to build the Great Granary and the Great
Warehouse in the whole account, with only a village effect artifact
+Fixed a bug in the Admin Panel map that didn't permit to show village
informations, if that village contained single quotes in its name
