D-rats client not reconnecting to repeater after disconnect

[wb8tyw]

When the d-rats client program gets disconnected from a repeater,it may report the disconnection for a few times.

When the repeater should be reachable again, it does not reconnect, and the only log message is that it is waiting 1.3 seconds before transmitting at the default log level.

The only way to get it to reconnect is to restart the d-rats client or going into the configuration for Radios.

Partial fix in place,
Needs Transport should have separate worker threads for transmit and receive
