Added support for Items to have a loot source attached to them when dropped or rolled. This fixes the issue where achievements would give the item before it appeared in the achievement window.
* Fixed tab indent
* Fully implemented Achievement tracking for Shooting Gallery
- Removed logging in MissionTask.cpp and moved the checks for mission progression to after checking the instance.
- Implemented the achievement tracking in SGCannon as well as tracking of the maximum hit streak and progression of enemy smashes in the shooting gallery.
