tableViews: remove dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath

Instead use dequeueReusableCellWithIdentifier:CellIdentifier.
dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath is only an iOS 6.0
method. dequeueReusableCellWithIdentifier:CellIdentifier works with iOS 5.0 and 6.0
Rotation: Fix rotation for iOS 5.0
