Changed:
Original routine advec_particles split into several new subroutines and renamed
lpm.
init_particles renamed lpm_init
user_advec_particles renamed user_lpm_advec,
particle_boundary_conds renamed lpm_boundary_conds,
set_particle_attributes renamed lpm_set_attributes,
user_init_particles renamed user_lpm_init,
user_particle_attributes renamed user_lpm_set_attributes
