- Handle CCS_NODIVIDER both when present and when not. 

- Handle some cases of CCS_TOP, CCS_BOTTOM, and CCS_NOPARENTALIGN.
- Handle values returned from the RBN_CHILDSIZE notification.
- Implement RBBS_CHILDEDGE.
- Fix some logic errors in REBAR_AdjustBands, and problems with CCS_VERT.

* 14. Handle returned value for the RBN_CHILDSIZE notify.
* 15. Implement RBBS_CHILDEDGE, and set each bands "offChild" at _Layout
