LOK: don't emit redline comments

Change tracking can be quite numerous. Showing the
markers (and their comments" as comment-boxes is
sensible where there is limited change in a doc.

However with extensively modified doc, this becomes
overwhelming both in terms of browser load and
editing performance. As such, we disable them
as they don't add much value. The user can still
access them from the Track Changes > Manage menu.

Use a rather nasty env. var hack to propagate this
setting from WSD for now.
