122320: Show closer after docking sidebar.  Prevent sidebar from being docked above or below edit view.

i122145 Two changes: Multiselection with mix of DrawObjects and OLE will allow LineStyle and FillStyle panel, single selection of OLE offers these, too, but in default closed state

support for recursive STL containers is not required by the standard.
Boost TR1 containers allow them explicitly though but for some compiler/stl
combinations there are constness issues that prevent the default
assignment operator to work. Adding a small helper function solves
this problem in a clean way.

i120935, Insert blank entry for RES_CHRATR_BIDITRL and RES_CHRATR_IDCTHINT, for keep the identical res order
