Fixes #162.
README: Add newer examples to avoid misleading people.

We had more than one issue filed where people thought that they only had to
specify the "base name" of the classes.

While this was true during the inception of Coursera, their naming of the
classes has changed during time and this makes the documentation clearer to
match the post-initial naming.
travis: Test also builds with pypy.
travis: Allow tests with pypy to fail.

Since people usually think of PyPy as a second-class citizen, we don't fail
in case one of our modules barfs with PyPy, but it is certainly a good thing
to test with it (and this author here would love to see PyPy become more
respected as it has the potential to make Python a high performance
language).
travis: Make nose tests verbose.

This way, we can easily see what works by names, instead of only seeing
little dots.
Update Python requirements in documentation.
Add required package six to the list of packages, as well as update instructions for requests package for Mac. In addition, add details on selecting python 2.7 for Mac Ports in order to get coursera-dl to find the required python libraries.
More informative error messages

I also think it should look up for the host coursera.org instead of
'coursera-dl'.

coursera: coursera_dl: Add tests for minimum versions of some modules.

We keep getting bug reports unrelated to our code. This addresses, in part,
issue #139, but there is more to come to fix that bug.
coursera: Fix test breakage with missing imported module.
coursera: Fix test breakage with missing imported module, take 2.

I am sleep deprived and should not be allowed anywhere near a computer that
