Add Page and Request Summary CSV files

Add Page and Request Summary CSV files to the Export menu

This fixes #1739

Thanks for doing this @paulcalvano!

Both these lines will need to be wrapped in double quotes (") rather than single (') for the variable interpolation to work.

So like this:

echo "<li><a href=\"/csv.php?test=$id\">Download Page CSV</a></li>";

Once that's fixed, we can ship this. :)
