updates for upcoming changes to LandR.CS

[achubaty]

LandR.CS is being updated to take in climate data using the list structure used by fireSense, to allow the user to pass arbitrary climate variables.

The module currently does this:

  ## objects for LandR.CS:
  sim$ATAstack <- climateRasters$projected_ATA
  sim$CMIstack <- climateRasters$projected_CMI
  sim$CMInormal <- climateRasters$historic_CMI_normal

  ## objects for fireSense:
  sim$historicalClimateRasters <- list(MDC = climateRasters$historic_MDC)
  sim$projectedClimateRasters <- list(MDC = climateRasters$projected_MDC)

and should be updated to put projected_ATA and projected_CMI into projectedClimateRasters, and historic_CMI_normal into historicalClimateRasters.
