The last default change was not quite correct, FIXED_HALO_GRIDS should be false by default, and HII_FILTER should be 0 (real-space tophat).
However, this exposed a previously existing bug where sometimes if this flag was on, the program tried to load an object which doesn't exist. This structure has been cleaned up a bit to make it clearer when to load the halofield objects.
