[arm-allstar] Update V1.5.3-48

[Doug Crompton]

There has been an update  V1.5.3-48 which fixes a problem, especially on
hubs with larger numbers of direct connections, greatly increasing the
efficiency of the link lookup loops. More sanity checks have also been
added. This is just another improvement to the hamvoip code and there will
be many more coming in the future.

There was a minor fix to AutoSky regarding display of the Alerts in
Supermon.

Use Admin menu item 1 to update.
