Changeset 2945

DEV: tested 1 year global. This code contains the latest version for anthropogenic tree species channges, several bug fixes to forest management as well as the code for the fully integrated multi-layer energy budget. This implies that the multi-layer energy budget makes use Pinty's albedo scheme, the rognostic canopy structure as well as a vertical profile for stomatal conductance. This is an intermediate version because species change code is not complete as some management changes have not been implemented yet. Further the multi-layer albedo code needs more work in terms of calculating average fluxes at the pixel rather than the PFT level
