Fixes quotes for alias registration

[spier]

Fixes #55, as the way that I got the alias to register correctly on OSX is:

git config --global alias.fame '!python -m gitfame'

Please note that
a) I have only tested this on OSX
b) I have not tested if on OSX I even need to register that alias at all

Hope this is still useful.

Can you delete the alias (git config --global --unset alias.fame) then try running git fame to see if it still works?

[spier]

Hah, that also works. So the alias really isn't needed on OSX then.

Not sure if the PR is still useful/valid for others then? Feel free to just close it without merging if it ain't useful.

Thanks for the help, and for the git-fame tool. I will play around with it in the context of this InnerSource pattern, in order to figure out which contributors should get some praise :)

added a note about different OS escapes, thanks :)
