Although this patch does enable ipython 0.11 to start in spyder
2.0.12, there still seem to be some problems:

- When I try running a script in the "current ipython", I observe the
  following exception:

/usr/lib/python2.6/site-packages/spyderlib/widgets/externalshell/startup.py
in runfile(filename, args, wdir)
    112     glbs = globals()
    113     if '__ipythonshell__' in glbs:
--> 114         glbs = glbs['__ipythonshell__'].IP.user_ns
    115     glbs['__file__'] = filename
    116     sys.argv = [filename]

AttributeError: 'InteractiveShellEmbed' object has no attribute 'IP'

- Created variables don't appear in the variable explorer.

Is the patch supposed to fix these?
