Merge pull request #1565 from ckeditor/t/1563

Internal: Removed usage of `WrapOperation` and `UnwrapOperation`, using `MoveOperation` and `InsertOperation` instead. Changed `SplitOperation#insertionPosition` to a settable. Renamed `SplitOperation#position` to `SplitOperation#splitPosition`. Closes #1563.
