Fission Engine extras: no heat from LV-N

[DerJere]

While using the Nerv engine with System Heat for the first time I noticed it wasn't working properly for me.
When I open the Nuclear Heat / Reactors HUD from the toolbar the console gets flooded with NullReferenceException's as long as it's open.
Also the temperature is shown as 9999/9999 K all the time while not actually having any significant impact on the vessel. It is possible to fire it with unlimited fuel cheated for as long as the uranium lasts and nothing overheats. HotSpot values on the parts show 400 K at maximum.

I already tried uninstalling HotSpot and only having the Nuclear Engine Config of SystemHeat installed - with no success.

Seems to be caused by lacking a ModuleSystemHeat in the patch.

Nertea says that only engines that need cooling would need the module, so just need to fix the code.

I've fixed the NREs, but the setup for these engines still seems weird. The HeatCurve is empty, so it never generates any heat
