[arm-allstar] Update V1.6-06 released

[Doug Crompton]

An update version 1.6-06 was released today.  It includes the binary nptee
(Named Pipe Tee) and a howto at hamvoip.org on its use. This SW allows
multiple streams from Allstar (outstream command in rpt.conf) to external
code such as lame and ezstream. It also decouples the external program from
Allstar so that no interaction exists when restarting or rebooting.

Also included is a new script called -  echolink_permit_deny

This script allows you to change the permit or deny calls for Echolink
without directly editing the config file. This still requires an Allstar
restart to take effect but makes it easier and less error prone to make the
changes. This is one step towards a change In the near future where the
Echolink permits and denies will be defined through the Asterisk database
in a similar way as the ban/allows are now for Allstar. Once it is done
this way the changes will be immediate with no restart required.

And finally the sleep was updated in astdb.php for up to 1800 random
seconds, rather than minutes. This should further ease the loading on the
hosting servers.
