Inserts a diff between two pages.  The "Diff.jsp" places two variables into the JSP PageContext:

* ''insertdiff.old'' - The version number of the old version.
* ''insertdiff.new'' - The version number of the new version.

These have been parsed from the HTTP parameters by "Diff.jsp".

The resulting HTML uses a few CSS styles:

* TABLE.diff - The whole table gets this style.
* TD.diff - Each unchanged line gets this.
* TD.diffadd - Each added line gets this style.
* TD.diffrem - Each removed line gets this style.
