Localization of the linearity of the shift functors #

If L : C ⥤ D is a localization functor with respect to W : MorphismProperty C and both C and D have been equipped with R-linear category structures such that L is R-linear and the shift functors on C are R-linear, then the shift functors on D are R-linear.
