Section 6.5 wrong link

[Bruce Wu]

On the table of contents page of the online textbook (http://www.math.toronto.edu/courses/apm346h1/20159/PDE-textbook/contents.html) if you click section 6.5 it redirects you to http://www.math.toronto.edu/courses/apm346h1/20159/PDE-textbook/Chapter6/S6.5.1.html which is not found. Instead it should be http://www.math.toronto.edu/courses/apm346h1/20159/PDE-textbook/Chapter6/S6.5.html

OK
