fix command currently broken on master

[hojerst]

The fix command seems broken after the recent merge of pullrequest #170

invoking "fix -l" will issue a error message about a missing "args.version" property.

Can you please paste the actual error message?

Just for clarity how i installed littlechef (on MacOS X 10.8.4):

# commit 87346e5db6302fad0085e56b53857cb599c57b01
$ git clone git@github.com:tobami/littlechef.git
$ cd littlechef
$ sudo python setup.py install

$ fix -l
Traceback (most recent call last):

commit 66a7ac65be71b41bff98417ff70c7d492c610a18 (release 1.5.2) works as expected running the commands above.

@hojerst thanks for reporting. This should be fixed now.
