[App_rpt-users] CTCSS and carrier squelch

The part regarding sending the CTCSS information in the IAX packet
is quite trivial, the problem is that the TX CTCSS selection is not
done in app_rpt. Its set and done in chan_usbradio for the USB
and in pciradio.c (hardware driver) for the Quad PCI card. There
is no direct and easy way to do this the way its done currently
and would be quite an undertaking to change it.
