Patch 27 - Achievements, Updated MoTD, Various

[Jack]

I will reboot the server in roughly 8 hours to apply a few fixes.

• Achievements will appear in leaderboards as soon as you have any progress in them.
  
• Achievement category ranks will display correctly.
  
• Achievements leaderboards will be eligible for re-sort every time achievement progress is updated for the achievement, instead of every time it is levelled up.
  
• The Visit Dungeons achievement will be fixed.
  
• Also fixed a bug with tournaments that I found by chance while testing this out.
