* Header control

* TODO:
* - Imagelist support (partially).
* - Callback items.
* - Order list support.
* - Control specific cursors (over dividers).
* - Hottrack support (partially).
* - Custom draw support (including Notifications).
* - Drag and Drop support (including Notifications).
* - Unicode support.

* FIXME:
* - Replace DrawText32A by DrawTextEx32A(...|DT_ENDELLIPSIS) in
* HEADER_DrawItem.
* - Little flaw when drawing a bitmap on the right side of the text.
