doge depends on argparse

[bukzor]

Doge works on python2.6 except that it doesn't necessarily install its dependency, in argparse.

Which is exactly what the README states:

Note that if you are one of the unlucky doges to still run a Python that does not have argparse (<=Python2.6) you will have to install argparse manually from pypi. so old, very update need.

I just couldn't be bothered in working around setting it as a dependency, as it did not work out of the box right away. It's a year ago so I don't really remember why - probably that everything above 2.6 stopped working. 2.6 is enough of an edge case in my mind that I just could not be bothered. If you make a patch that works on all systems and installs argparse np then I am happy to merge it. I myself have no real reason to do it though, but please feel welcome to experiment!

Do not depend on argparse if installing for Python versions, which include argparse
