LuaForce::reset_evolution()

[Bilka]

Currently setting the evolution factor does not change the percentages that are displayed when the /evolution command is displayed. Usually this would be "fine", but when setting the evolution factor to 0, the percentages really don't make any sense. So it would be nice if there was a way to either set those percentages or to reset both the percentages and the factor to 0, using LuaForce::reset_evolution() as proposed in the thread title.
