[paho-dev] RSMB - will messages

Does RSMB fully support MQTTSN will messages?
RSMB will request a willmsg and willtopic if I set the will flag in a connect message however I find my will message is never sent if my node goes offline.

Also I found a bug in the embedded C MQTTSN library which stops you from receiving MQTTS_WILLMSGREQ and MQTTS_WILLTOPICREQ messages as they are only two bytes long. (see below for the one line fix)
