Changes to list peers and users in alpha. order, as per a reasonable request in 12494. Due to changes in trunk to use the astobj2 i/f in the sip channel driver, the order of the entries in the config file was lost, thus the output was in a random order, but no longer.

    lost packets.
  * Added t38pt_usertpsource option. See sip.conf.sample for details.
  * Added SIPnotify AMI command, for sending arbitrary SIP notify commands.
+ * 'sip show peers' and 'sip show users' display their entries sorted in
+    alphabetical order, as opposed to the order they were in, in the config
