Achievements 7.x-1.4, 2011-11-10
--------------------------------
 * achievement-latest-unlock.tpl.php added and used in the leaderboard.
 * All template files have been moved to templates/ subdirectory.
 * Most .tpl.php $variables are now render arrays instead of strings.
  * This allows for easier modifications in preprocess hooks.
  * You WILL need to modify any overridden themes to support this.
  * You should be able to just replace "print $a" with "print render($a)";
 * "image_path" added to themes for the context-aware image path.
 * "achievement_title" added to themes for easier linked title display.
 * "achievement_points" added to themes as a renderable "$n points" string.

 * "achievement-leaderboard-top-rank-[123]" CSS class added to top 3 rank rows.
 * theme_achievements_group_wrapper() added (wraps around user/#/achievements).
 * theme_achievement_group_wrapper() added (wraps around an achievement group).
 * Stats on user/#/achievements are themed with theme_achievement_user_stats().
