  - FIX: An issue where the achievement height is incorrect after a loading.
  - FIX: An issue where the description of all achievements is wrapped after to have tracked one, causing  also height problem.
  - CHANGE: Tuned the position of achievement description and its objectives.
  - NEW: Added a new element id "achievement.description" for customizing the achievement description text . By the way, a new tab "Description" has been added in the achievement options.
  - FIX: Some typo
  - CHANGE: The minimum value allowed for the width of tracker in the options, it's now 200 (from 270). I don't recommend to use too small values.

NOTE: Following to theme system rework and some db structure changes, i couldn't migrate your appearance properties (e.g, tracker background) in the new version, so you will lost them.
Sorry for that, in the future, i will no longer encounter this issue.

I'm going to make later a post for showing more in detail the changes contained in this patch.
