The engine implementation of `print` packs the varargs into a table and passes the table directly to `table.concat`. If you pass any value not supported by `table.concat` (particularly `nil`), the server crashes. This is unexpected behavior, as `print` is supposed to be able to work with anything. This patch changes the implementation so it first converts all arguments using `tostring`, which fixes the issue and makes the custom `print` function compatible with the stock Lua behavior.
