Adding a separation of remote authentication and our authentication.

Browse Source 
remotesecret => our password for a remote service
secret => our authentication when someone calls us

Secret => still has both functions if remotesecret is not used.

@ -11,6 +11,10 @@ SIP Changes
making the new/old message count available to local devices.
* Added support for setting the domain in the URI for caller of an
outbound call by using the SIPFROMDOMAIN channel variable.
* Added a new configuration option "remotesecret" for authentication to
remote services. For backwards compatibility, "secret" still has the
same function as before, but now you can configure both a remote secret and a
local secret for mutual authentication.
