[2.0.11] Nuclear reactor UI temperature vibrates aggressively

[SteelGiant]

The temperature in the reactor UI on the temperature bar vibrates wildly as the temperature is being printed to a variable number of decimal places. While heating, it was essentially impossible to read as the temperature displayed was alternating between 1 and 2 decimal places an being updated every frame.

Suggest the temperature is printed in this UI at a fixed width to prevent movement. This problem is not so obvious in the info window under the minimap as that display only updates every second or so, not every frame.
