Patch to work with chan_dongle

[dandantheitman]

I've been trying to use this package with chan_dongle and had to make some changes. They are below if you want to consider including them in the next release. Changes are to trunkbalance.php, added lines are 365 to 378 below.

342                 switch ($destrunk_tech)
343                 {
344                         case 'sip':
345                                 if ($count_inbound) {
346                                         $channel_filter="(dstchannel LIKE 'SIP/".$destrunk_channelid."%' OR channel LIKE 'SIP/".$destrunk_channelid."%')";
347                                 } else {
348                                         $channel_filter="dstchannel LIKE 'SIP/".$destrunk_channelid."%'";
349                                 }
350                         break;
351                         case 'iax':
352                                 if ($count_inbound) {
353                                         $channel_filter="(dstchannel LIKE 'IAX2/".$destrunk_channelid."%' OR channel LIKE 'IAX2/".$destrunk_channelid."%')";

361                                 } else {
