Add some new protocol functions, which needed changes in the existing structure of the parameter part. New protocol functions are USEND, AR_SEND, and a basic dissection of Data record routing. Changed detection of mode transition events. USEND and mode transition events need a special handling (it's all reverse engineered, so it's still not 100 percent correct). Renamed "Prog" to "TIS" (Test and installation), and "Push" to "Indication" to use some of the official terminology. Cleanup of comments due to the changes, and remove some obvious ones.
