jens 616cf113f2 Mirror raw sensor temp through when the controller isn't configured yet
is_configured() (Smith's model plant params, only ever set once a Sud
loads) gates TcTask's call to tc.process() - the only place theta_ist/
heatrate_ist/heatrate_soll get updated and broadcast. Right after
server start, before any Sud has ever loaded, that left them frozen at
their __init__ defaults forever, so the GUI's Ist Temp/Rate and Soll
Rate displays never showed anything on connect. Mirror the raw sensor
reading through instead, with rates at 0 since there's no controller
output yet.
