Remove old-style print calls in setup.py (fix install with Py3)

[GuillaumeDerval]

Old-style prints currently make impossible to install PyLTI with Python 3

(there are other issues with Py3, but I'm investigating :-) )

Coverage remained the same at 100.0% when pulling a4a2fd4 on GuillaumeDerval:py3 into 3266843 on mitodl:master.

@amir-qayyum-khan would you mind reviewing this?

For info, there is a problem with an old library (oauth) that is not compatible with Py3, I'm attempting to convert PyLTI to oauth2 (which is a fork of the original oauth, and still implements OAuth 1, despite the name).

I do not really understand why PyLTI has currently a dependency on both oauth and oauth2, as they do exactly the same thing... Is there a particular reason?

[amir-qayyum-khan]

sure let me

I spent some hours to make PyLTI pass the tests again with Python 3 (tested with 2.7, 3.4 and 3.5, I'm not sure it will pass with Python 3.1, 3.2 and 3.3 since they don't support the u prefix from what I remember):

However, I have not tested if it works in any practical situation. I'll make some tests in the following days, then I'll open a PR.

I dropped oauth, since oauth2 is a fork, but oauth2 itself has some problems, which I had to fix manually (see classes SignatureMethod_HMAC_SHA1_Unicode, SignatureMethod_PLAINTEXT_Unicode, Request_Fix_Duplicate) (joestump/python-oauth2#207 joestump/python-oauth2#197).

There are a lot of problems with encoding everywhere.

It also fixes #58

close in favor of #61
