Subversion: use version 1.7 of the svn book

[AnthonyMastrean]

The svn "fathead" links to out-of-date docs (1.5). The latest is 1.7 and 1.8 is in draft now.

@AnthonyMastrean thanks a lot for reporting this!

The linked file isn't actually the code that's being used in production, it's code from a developer who wrote a scraper for SVN that he's "donated" to use in case any devs out there feel like adapting it for a Fathead Instant Answer.

This is actually a "legacy", internal IA which will need to be fixed internally.
