[Lazarus] New Tabcontrol: compiler warnings

[Bart]

Hi,

When building r33461 I got the following 2 warnings:
E:\LAZARUS\lcl\comctrls.pp(852,15) Warning: An inherited method is
hidden by "TTabControl.Change;"
E:\LAZARUS\lcl\comctrls.pp(853,14) Warning: An inherited method is
hidden by "TTabControl.GetImageIndex(LongInt):LongInt;"

Not sure if this is by design or should they be declared as override
instead of virtual?
