For issue #121 ("1.7 change: copy-on-update code removed").

* en/book/ch02-basic-usage.xml
(svn.tour.treeconflicts.example): Rework this section a bit for
clarity, for updated output from Subversion 1.7 binaries, and to
not depend on Subversion applying edits atop of moved file
automatically (since we removed that logic in Subversion 1.7).

changes in unidiff format, except for svn:mergeinfo properties").

and massage wording about how properties are represented to include
a mention of 'svn patch' and its utility here.
