Support 64-bit integers

If a 64-bit integer is deserialized or constructed, it is not returned
as number, like the previous 32-bit integer was. It is wrapped in an
object with the __type "integer" and the value is stored as string;
64-bit size is expected  be reached by IDs, which do nit take part in
numeric computations.

Checking for maximum numbers in deserializing and constructing improved.
