New typemaps for wxString when compiling for Python 2.0 and beyond

that allow Unicode objects to be passed as well as String objects.  If
a Unicode object is passed PyString_AsStringAndSize is used to convert
it to a wxString using the default encoding.

Fixed the generic buttons so tool tips work for them.

Fixed a bug in the demo's tree control.

Added a listbox to the listbox demo that shows how to find items with
a patching prefix as keys are typed.

Added code to the wxListCtrl demo to show how to get text from a
column in report mode.

Added code to the toolbar demo to clear the long help from the status
bar after 2 seconds.

Added wxJoystick.

Fixed wxTimer so it can be used as described in the docs, either with
a Notify method in a subclass, or sending an event to a wxEvtHandler
object, (usually a window.)

Added wxNotifyEvent.Allow()
