APRS TX app is working fine now!

Browse source 
Several old bugs squashed.

On the APRS side, most notably, SSID numbers where shifted left twice, instead of once, and bits 5,6 where not properly set.

On AX.25 side, the bit stuffing part of the encoder was not placing the zero bit on the right place.

Finally, I changed APRS icon from ORANGE to GREEN, since even this may be a simple app, now it's doing its work as intended.
