Expect test_get_friends to raise RedirectException

get_friends is a bit tricky to test, as it awaits a fix upstream.
See issue #175 Until that happens, it will remain broken. However,
having a test where the expected behaviour is to fail is wrong.

This commit mean that in the future, the problem will be solved and
this test will now fail in this version of PRAW. Therefore,
documentation has been added to show that this is actually not a
problem to any users running the test suite for this version in the
future.
Note activity req for subreddit recommendation
Clarify 2 docstrings. Fix #268. Thanks Kodiologist
Add support for storing JSON response. Fix #263.
Convert relative URLs to absolute URLs.

The usage of relative URLs such as www.reddit.com/r/TheDailyPrompt
that do not include the network protocol will create a link to
a page on RTD. In this case
https://praw.readthedocs.org/en/latest/
pages/www.reddit.com/r/TheDailyPrompt

This commit changes all relative urls to absolute urls by prefixing
the urls with 'http://'.
