FastObjectListView - MoveObjects() attempts invalid insertion with index -1

[PyroGenesis]

When I used MoveObjects() with an index of 0 with a collection of objects that includes the first object (at index 0), I get an IndexOutOfRangeException because it will try to insert objects at index -1.

I narrowed it down to this block of code in MoveObjects():

ObjectListView/ObjectListView/FastObjectListView.cs

Lines 123 to 128 in 8a10cbd

	foreach (object modelObject in modelObjects) {
	int i = this.IndexOf(modelObject);
	if (i >= 0 && i <= index)
	displacedObjectCount++;
	}
	index -= displacedObjectCount;

Since, the first object (at index 0) will satisfy the if condition, the index will be decreased from 0 to -1.
Should this condition be changed to if (i >= 0 && i < index) instead?
