Add wxArtProvider using Tango icons.

The icons are embedded as PNG images directly in the source code to avoid the
need for installing them. This does make the library larger though so provide
a wxUSE_ARTPROVIDER_TANGO option to turn the new code and associated bloat off.
Also turn it off by default under wxGTK as the native art provider is used
there anyhow.
