Subject: [PATCH] Add support for Cocoa's selectable toolbar items.

The support is currently limited to making all toolbar items selectable
and is only available in wxOSX with Cocoa and native toolbars.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@73575 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
