Merge lp:~robru/friends/quote-urls into lp:friends

[Robert Bruce Park]

Properly quote long URLs when submitting them for shortening, so that they don't break in transit.

Ok, so while I was refactoring the url-shortening logic for trunk-next, I realized that we weren't quoting the URLs to be shortened, which was resulting in some pretty bad breakage in certain cases. For example, if the URL contained a plus-sign (such as the one you're looking at *right now*), the URL shortener would interpret that as a space, and then the shortened URL wouldn't point at the real URL you wanted, but at s/+/ / instead, which obviously breaks the link.

So I fixed that by running the URLs through urllib.parse.quote before submitting them for shortening, and I included a test case to ensure that the strings really are percent-encoded before going out over the wire.

Please merge this in time for raring!
