Ipython.gui.wx.ipython_view.IPShellWidget: ignores user*_ns arguments

[ElectronicRU]

When creating IPShellWidget and passing it user_ns and user_global_ns arguments and not wx_ip_shell one, it does not pass these two to WxNonblockingIPShell constrctor, as one can expect. Since it's hard createWxNonblockingIPShell working outside of IPShellWidget constructor, there's no normal way to pass user namespace. It looks like a typo. Please fix it.

IPython.gui.wx is no longer supported unfortunately, but pull requests are welcome.
