[FYI] Adding delivery reports to ppg

Hi List,

i now have code for ppg delivery reports. It use dlr-url and drl-mask, 
quite normal Kannel style.
But there is one thing: dlrs are delivered by smsbox, so the use must 
define one. And there
must be smsbox-id defined for smsbox sending the dlrs and service-name 
for ppg (smsbox
will names).

However, I think it is better that smsbox sends the delivery reports in 
all cases. Only wap over
sms would merit wapbox handling of mo sms.
