[Lazarus] Adding and hiding TPageControl tabs

Thanks, I'll investigate upgrades.

I'm not trying to hide the tab but still see the page, I'm trying to 
hide the entire page+tab+content (index zero) and only leave the 
newly-created one (again, page+tab+content). But the last time I did any 
of this was around about the time that the old TNotebook etc. was 
deprecated, and I'm assuming that the rather convoluted sequence I was 
using in those days is no longer appropriate.

It hides everything at [0], but also hides the content of [1].
