SQL: Update was required after [4241], so cleaned up core a little to prevent such issues in the future all together. Now the zone names can be changed as many times as needed, just don't change their id. Thus, I changed the structure of grandboss_list a little and this requires [L1822] and the sql update in this commit. Fixes #L2241, thx L2Nemesis for reporting.
