changed MarkAsDone for the different views
fixed bug for delete and changed commandSearch for view
changed mark as done so thats the completed task are at the bottom
still 2 bugs remaining
1. after done tasks if we add floating they will be below the completed tasks but thats not a problem as we are segregating the views
2. Have to fix initialising the displayList as the storageList for the first time
Changed commandSearch so now no search within search
