Fixes #5483 This only applies to "base game" spells. When adding an AutoCalc spell with TES:CS its cost is computed and stored inside game files. This stored cost was being used by OpenMW and the actual cost was never recomputed at runtime whereas Morrowind.exe discards the stored cost. While this worked fine in vanilla, mods can update AutoCalc spell effects without ever updating the stored cost. The formula was mostly there already but there was a few differences, namely a 1 second offset in duration.
