if MAX_NUM_SOIL_TYPES is 15 then the Bushland simulation does not run correctly

[peterlafollette]

Minor issue where the LASAM simulation for Bushland doesn't run correctly. This is because MAX_NUM_SOIL_TYPES as defined in all.hxx was recently changed from 25 to 15, and Bushland uses soil types from a .dat file with more than 15 types. MAX_NUM_SOIL_TYPES has been reverted to 25 in the LGARTO branch, which fixes the issue. My opinion is that generally MAX_NUM_SOIL_TYPES should be greater than 15 in the event that a user wants to define a larger number of soil types, however I also see the reasoning for restricting MAX_NUM_SOIL_TYPES to be a smaller number.
