Customizing Allstar

Customizing actions of the ASL node isn’t all that complicated. Everything can be setup in /etc/asterisk/rpt.cfg under the [functions] section:

added *77 to announce IP to help find it on DHCP on WIFI (hotspot):
```
77 = cmd,asl-say -n 63047 -w ip4
```
added *78 to shutdown the node via DTMF
```
78 = cmd,shutdown now
```
ensured I could disconnect all with *6
```
6 = ilink,6
```
made the node fire that *77 command on startup by adding to the (node-main) section for my node:
```
startup_macro = *77
```
