ASACORE-46: Thin Client applications don't know the full service name

 - The function AJ_StartClient() connected to the first service it
   found that matched the prefix passed in. If the name passed in
   wasn't the full name any subsequent method calls would fail.

 - This change added a new function AJ_StartClientHelper() which is
   identical to AJ_StartClient() except with an out parameter which
   will be filled with the full service name that you connect to.
