Axel Dörfler 09d87d9151 The text control is now more flexible with its layout items.
* Before, you had to have both, the text view layout item, and the label
  layout item or else nothing would ever be visible.
* Now you can only create the text view item, and it will still work.
* Also, no matter the order you added the layout items, they would always
  put the label on the left, and the control to the right.
* You can place the label and text view layout items anywhere now, although
  you should keep in mind that the view spans over their frame unions; IOW
  they should always adjacent to each other, but not necessarily horizontally
  and left to right.
* No longer uses a fixed label spacing, but utilizes
  BControlLook::DefaultLabelSpacing() instead.
* However, the spacing is always added to the right of the label, no matter
  how you place it in the layout. Maybe one wants to add a SetLabelTextViewGap()
  like method.
