[arm-allstar] speaktext.sh

Attached is a shellscript I wrote based on the questions I had about 
making the radio transmit and sending speech.

I'm using this to output information from my local environment using 
another script that fetches this for me from DTMF commands. That other 
script is yet to be written but I do have it for IRLP. Just need to 
adapt it to Allstar.

To use just enter text in quotes and the node to send it to. It is still 
a work in progress but useable

Example syntax is:

./speaktext.sh "IP 192.168.1.20" 28727
