Fixed a few bugs related to the overhaul of the Event Engine.
- Failure of TLKCenteredList<T>.DeleteCenter to decrement the Right Array Count when shifting the first element of the Right Array into the Center.
- Added Center Finalization (so that the reference will be nulled when the item at Index 0 is removed)
- Found a type mismatch issue in LKSL.Events.RecorderFile.pas when storing the Event Count (writing initially as Int64, storing an Integer value in that part of the stream... basically, overflow issues).
