Added direct calculation of the mesh forces when checking accuracy. Use higher-order CIC interpolation when translating the mesh back to the field tensors.

Pass an extra argument to the function returning the particle's softening. Removed the field from the gpart themselves.

Better function name for the first initialiation of all the parts at the very start of engine_init_particles()

Corrected the softening kernel. Modified the Plummer-equivalent constant. Created place-holder for order 3 softened M2L kernels.

Compute the total mass in the system and add a variable to the gpart to record how much mass they interacted with via self-gravity.
