Changes

* Some items require certain conditions to be improved. For example, [[smithing]] items need to be [[Temperature|glowing hot]] to improve. Also, most items need to be at 0 [[damage]] (repaired) to be improved, except [[wooden fence]]s, wooden [[gate]]s, and [[stone wall]]s.

* Some items cannot be improved and will reflect that when the examine command gives no information for improvement: [[newbie]] [[starter kit]] tools, most building materials ([[Pile of dirt|dirt]], [[plank]]s, etc), [[yoyo]], [[raw materials]] (but can be combined with higher [[quality]] material to improve (at the expense of the higher quality material), unrepairable items]], etc.
