[aprssig] Tracker2 display

The Tracker2 has had LCD support for a while now (and the OT1+ even 
longer) but I hadn't ever gotten around to documenting the hookup 
properly.  I just posted some information here:

There's no configuration, it just works automatically with the current 
firmware.  Right now you just get one display - callsign, distance and 
direction, and comment text.  I'll add more information as time and code 
space allows.

I may rearrange the pinout slightly in the future to add a keypad.  I've 
got a prototype working, but so far it doesn't do anything more than 
tell you which of four keys you pressed.

Come to think of it, it'd be pretty easy to add a few more 'keys' (it's 
reading different resistor values for each key) and assign them to fixed 
functions like 'beacon now' or to macro functions, so you could make up 
your own custom control panel with whatever combination of buttons you 
want.  Hmmmm..
