Warning message on variable_get call in Express Checkout

Hi,

Just a small request: on line 1100 of the .module file in the beta5 version there is a call that generates an annoying warning:

variable_get('uc_payflowpro_ec_reqconfirmed_addr')

This syntax is sadly only OK for D7 and D6 or before still requires a default value to be submitted.

Thanks for fixing.

Martin
