Rename fix python/integrate to python/move

This is to avoid confusion to what LAMMPS considers to be an
integrator like Verlet and RESPA.

+   force cutoff distance in the absense of pair-interactions or
+   with hybrid/overlay if a larger force cutoff distance is required.
+
+   This can be used in conjunction with bond/create to create bonds

+   calculate radial distribution functions for models without
+   pair interactions.
