FMod - Resource Accountant improvement

One Abiathar user requested the ability to count how many of each kind of resource item are in the level, e.g. the number of 500-point items, in addition to how many total resources of each type there are. I implemented that today along with a new configuration option to control whether that new information is shown. The list is currently sorted by instances of the resource item kind, though that can look a little strange and might be changed.
