Dirty hack evasion / registration ease-up #133

There's a mix-up with SDP building packets on red5phone. I was trying to run up 
the sip/rdp connection through an openvpn tun interface. It registers just 
fine, but is unable to be validated, because packets are returning to the 
viaAddress on the initial header. The red5 machine has  eth0 and tun0 
interfaces. If i register to my asterisk via "the internet"(e.g eth0) it is ok, 
because the handshake goes with the address of the eth0. If i decide to connect 
via the openvpn tunnel i can see the packets through it, but the header on the 
debug console states "sip:user@eth0.ip:port". I took a peek at the src and the 
initial SDP and the RegisterClass are taking a property viaAddress from a 
regular getHost routine. This is appropriate in most of the cases, but not mine 
in particular.
I ended up setting the hostname environment variable to "10.10.5.10", which is 
my tun0 ip, so that it would function correctly again.
There's an issue posted here with a similiar problem which builds up the 
viaHeader with 127.0.0.1. You can again fix it with a simple `hostname your.ip` 
before running red.

My suggestion is that a new configuration variable is introduced for just those 
cases and control is more straight-forward.

Thank you.
