Reassigning to tasklist. There is some place for improvement in TaskList class. ArrayList can be replaced by HashMap in setTasks() to speed up contains() and LinkedList(s) can be replaced by ArrayList(s).

Log: Issue #225812 - org.netbeans.modules.tasklist.ui.TaskListModel.getRowCount: LowPerformance took 33250 ms.
Performance changes. Replace ArrayList by HashSet due to performance issue when calling contains method. Also replace some LinkedLists by ArrayLists - faster iteration.
