sms: Increment the RP Message Reference for each transaction
Each RP-DATA should have a unique msg reference. Currently 42 is used for all of these. Remember the last reference we used and increment it on the next SMS. Do not track if the reference is still in use a clash is a lot less likely now. First unless SMPP is used only one SMS is delivered at a time, second the transaction space is a lot smaller than the one for the reference.
