[aprssig] New OpenTracker+ features

The changelog's been lagging behind since the introduction of the OT1+. 
  I'll be working on getting the website up to date soon, and that 
should help clarify things.  Right now, I've got the following active 
products:

OT1m - OpenTracker 1 series in a metal enclosure.  Limited by 
availability of the MCU, soon to be discontinued.

OT1+ - The current through-hole kit.  Includes all the features of the 
OT1 and adds RX capability, expanded telemetry features, and easier 
tuning and diagnostics.

OT1+ SMT - Functionally the same as above, but in a 24-pin DIP form 
factor, like a Basic Stamp II.  Good APRS MIM replacement.

T2-135 - A Tracker2 board that goes in the Alinco DR-135T. 
TNC/tracker/digi/wx, Garmin binary support, and so forth.  Currently in 
limited production until I get the kinks worked out of automated assembly.

I also have a few OT1x kits left, or parts for them anyway, but I'm 
taking them off the website to reduce confusion.

OT2m kits - the Tracker2 in the same metal case as the OT1m - are 
available from time to time as I get boards in and make up beta test 
kits.  Currently all of the betas are on rev C.  Rev D was the first SMT 
version and had too many errors to be useful.  Rev E is on the way now, 
and if it works out it'll be the first production version of a 
standalone T2.
