New issue 375: iyt is hard coded to only work with ipython 0.10 or 0.11 and crashes with 0.12

Description:
  The iyt script raises an exception if the ipython version is not 0.10 or 0.11 (0.12 is out already, and 0.13 is the current dev version):

{{{
Traceback (most recent call last):
  File "/opt/local/bin/iyt-2.7", line 30, in <module>
    if api_version == "0.10" and "DISPLAY" in os.environ:
NameError: name 'api_version' is not defined
}}}

This is due to the following if-statement, which has no else clause:

{{{
if IPython.__version__.startswith("0.10"):
    api_version = '0.10'
elif IPython.__version__.startswith("0.11"):
    api_version = '0.11'
}}}

I think there was an API overhaul in 0.11, but 0.12 and subsequent versions should keep that API, so I think you could add an else:

{{{
else:
    api_version = '0.11'
}}}

This seems to do the trick for me. The reason I came across this is that I am maintaining yt in MacPorts, and ipython in there is already at 0.12, so I am going to have to patch the iyt script as above so that it works.
