Merge pull request #1296 from fperez/wxgui

Fix the broken example for `%gui wx`
It seems our Wx code was OK, it was just a problem with the example.

Closes  #645

 A Simple wx example to test IPython's event loop integration.
 
 To run this do:
 
-In [5]: %gui wx
+In [5]: %gui wx  # or start IPython with '--gui wx' or '--pylab wx'
 
 In [6]: %run gui-wx.py

-This example can only be run once in a given IPython session because when
-the frame is closed, wx goes through its shutdown sequence, killing further
-attempts.  I am sure someone who knows wx can fix this issue.
-
-Furthermore, once this example is run, the Wx event loop is mostly dead, so
-even other new uses of Wx may not work correctly.  If you know how to better
-handle this, please contact the ipython developers and let us know.
-
-Note however that we will work with the Matplotlib and Enthought developers so
-that the main interactive uses of Wx we are aware of, namely these tools, will
-continue to work well with IPython interactively.
