Importing original deals

To be able to import original deals, contract contains method importOldDealPurchase. This method allows to configure deal purchases without transferring real token. This feature is enabled only during deployment and after that it is revoked by revokeImportingOldDealPurchases. After revoking, there is no way how to enable it again and there is no way how to create deal purchases without money transferring.

• allowedImportingOldDeals - info about importing enabled
