Update version support.

Add support for Graph API 9.0, 10.0 and 11.0. Removed support for deprecated versions.

I'm afraid that errors in CircleCI are caused by the Facebook App used for testing (probably is consuming Total Usage Rate in any way). The only error I get, running tests locally and using my own Facebook App, is:

======================================================================
FAIL: test_parse_signed_request_when_correct (test.test_signed_request.FacebookParseSignedRequestTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/sergio/src/facebook-sdk/test/test_signed_request.py", line 31, in test_parse_signed_request_when_correct
    self.assertTrue(result)
AssertionError: False is not true

And I guess I get it because my FACEBOOK_SECRET belongs to other used to the one expected with the hardcoded payload on the test.

So I don't know how much can I do to fix them.
