Record: type cast page_namespace into int; make submission_id a string

The version and/or configuration of the MySQL client can apparently mean
we get a string instead of an integer, causing the page titles to be
displayed incorrectly.

For good measure, we type cast all getters that should return an int.

The submission_id meanwhile can either be an int or a string, depending
on whether it's from the new Turnitin API or the old one. We cast to
string since we don't need the integer type for this field.
