After a LCC r6265 was looking for the PFT with the largest fraction to add the residual cover fractions to. The PFT with the largest fraction could be in age class 2, 3 or 4. By definition an extension of a PFT (in this case adding the residual) should happen in age class 1 (= the youngest age class). In r6271 the code was rewritten to search for the largest PFT of age class 1. The opportunity was used to simplify the code a bit by making a subroutine for cleaning the variable loss_gain. The variable failed_vegfrac was added.
