Wrong tag order for APRS packets with altitude and range

Current APRS packet sending altitude (/A=) and range (RNG) is wrong resulting in data misinterpretation showing RNG tag as comment. This is a result of wrong tag order.
According to APRS spec http://www.aprs.org/doc/APRS101.PDF chapter 7 and 8, RNG is a special tag for range and is supposed to be sent before comment while /A= tag is a comment tag.
Packet
SP5LG-B>APDG02,TCPIP*,qAC,SP5LG-BS:!5215.03ND02101.33E&/A=000000RNG0000 440 Voice 439.90000MHz -9.5000MHz
Result as seen on aprsdirect.com

Your patch is good. I’m waiting to get a chance to check the other modes APRS code for the same bug. It will be committed when I get a chance to check.
