Remove dependencies of 'harvested' dimension not connected to harvests

[jonathanholder]

The 'harvested' dimension in the output (modOut[,,,2]) will be replaced by an array for harvests (~old energyWood array); there are a few references to this that are not directly linked to harvests (and won't be included in the new array), which should be redirected (list might not be exhaustive):

core Prebas (B_prebas.f90)

• fertilisation (?) / par_alfar, e.g.
  

  Rprebasso/src/B_prebas.f90

  Line 235 in a1369fd

  par_alfar = modOut(year,3,ijj,2) * age_factor

• gammaC / thinClx, e.g.
  

  Rprebasso/src/B_prebas.f90

  Line 1584 in a1369fd

  output(:,1:2,1,2) = thinClx

regionPrebas (C_regionPrebas.f90)

• flag for clearcut/thinning compensation, e.g.
  

  Rprebasso/src/C_regionPrebas.f90

  Line 467 in a1369fd

  multiOut(siteX,ij,1,1,2) = 4. !!!flag for thinning compensation

  
  and
  

  Rprebasso/src/C_regionPrebas.f90

  Line 607 in a1369fd

  multiOut(siteX,ij,2,1,2) = 2. !!!flag for clearcut compensation
