Core/Worldserver: Enable the database updater by default.

* Seems like this feature is stable enough to enable it by default
  since the last missing bugs were fixed some months ago.
* The database updater is the preferred method to update the databases
  as described in the wiki: http://collab.kpsn.org/display/tc/Databases+Installation

(cherry picked from commit 25185967e8df949e0f13ec0a7ff45b14ba977c76)
