Subject: [PATCH] Pre-init pot temperature input with ambient temp on first
 server push

Mirrors PyQt client which seeds doubleSpinBox_pot_temp from the
remembered ambient on startup. In the browser there is no persistence,
so the first AmbientTemp message from the server is used instead.
Flag resets on reconnect so it re-syncs if the server restarts.
