Important new feature: pseudo service codes

The IGeneralInvoiceRequest::AddService method has been patched to allow for controlling the underlying validators by using a pseudo service code:
where cmd=value are validator specific commands. In such a case besides the service code (bstrCode) only the tariff type (bstrTariffType) and date (dDate) must be defined.

Currently there are defined pseudo codes for the following tariff types/validators in effect:

Pseudo codes are active until the next call of the IGeneralInvoiceRequest::Initialize method and are then reset to their default values.
Do not use pseudo service codes if the validator is turned off by setting eIgnoreValidate=enYes!
