'TSpTBXSkinStatesType' not found

[Ludens1]

To reproduce this another ancient issue:

1. Create new blank project.
2. Drop down SpTBXButton1.
3. Create any SpTBXButton1DrawCaption handler.
4. Get compile error
   [DCC Error] Unit1.pas(14): E2003 Undeclared identifier: 'TSpTBXSkinStatesType'.

That's not critical.
We can add SpTBXSkins to 'uses' declaration with our hands.
But we love perfection :)
