What has been changed in TPageControl

TNoteBook is not (any more) related to TPageControl, and (now) doesn't have visible tabs/pages.

I found this workaround:

1) Open the project in an older Lazarus version, which supports the old version of TNoteBook.

2) Add a TPageControl.

3) For every notebook page do a Cut&Paste into a new Page. Copy won't work, because the controls are renamed by Paste! Update the Caption of the Page.
