Wraps long lines in bulk email messages.

RFC 2822 states that line lengths in emails must be less than 998.
Some MTA's add newlines to messages if any line exceeds a certain
limit (the exact limit varies). Sendmail goes so far as to add
'!\n' after the 990th character in a line. To ensure that bulk
mail messages look consistent long lines are wrapped to a
conservative length.

Switch PDF Textbooks to use portable URLs
Fixed transform_url function in WikiAccessMiddleware.

In the current implementation if the path prefix contains the
wiki_path value it gets deleted. For example if the prefix is
'/courses/edx/math101/2014' and wiki_path is '101/' the final
prefix becomes '/courses/edx/math2014'.
