warnings patch submission

The following patch should get over the (in this case cosmetic) warning:
> ./gqb/gqbView.cpp: In member function 'void gqbView::onMotion(wxMouseEvent&)':
> ./gqb/gqbView.cpp:344:16: warning: converting 'false' to pointer type 'gqbObject*' [-Wconversion-null]
> anySelected = false;
> ^

==================================================================
On the other hand, the maintainer may wish to take a look at the
following warnings in pgadmin/ogl/drawn.cpp:
