RecyclableList.LastTakenBlockIndex property added for some scenarios.
RecyclableList.IndexOf & .LongIndexOf fixed to use the correct index.
RecyclableArrayList.AddRange(RecyclableList<T> items) fixed to use the correct index.
Some test cases excluded, where needed.
RecyclableList.Clear will no longer create new arrays. It will only release the array to the pool & decrease capacity.
Fixed possibly infinite loop in Clear.
