gh: Trending reporting error

[RupGautam]

Trying to pull trending topics and I got that error.

Listing daily trending all repos...
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/feedparser.py", line 399, in __getattr__
    return self.__getitem__(key)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/feedparser.py", line 348, in __getitem__
    return dict.__getitem__(self, 'updated_parsed')
KeyError: 'updated_parsed'```

Thanks for filing the issue, I can also reproduce it. Seems the GitHub Trends RSS data format has changed and is causing the issue.
