Implement complete set of APRS queries

[godfreja]

Email request from Cyril - DF1CHB - F1MHV

Could-it possible to implement the complete set of APRS queries such as http://privat.bahnhof.se/wb758759//documents/APRS-Queries.pdf ?

Or more simple: to get the possibility to send them manually via the message box implementing a rule that any message beginning « ? » (i-e: ?APRSP) should be sent without the ack characters.
