At present expirydate is calculated when needed for a subscription. As a result
it is not available for e.g. sql reports. As this means that the site cannot
get a count of active subscriptions (definition being that they have not yet
expired) basic management info cannot be retrieved.
Storing the the expirydate will also allow some improvement in the efficiency
of the serials code as in order to get the field the code currently reexecutes
the fetch of subscription data just executed.

Testing has shown some anomalies in the existing expiry date code.
(calculations for 32 two-weekly issues are giving a date far too soon). 

Code should ensure that expiry date is set correctly after add and modify
operations on subscription
