This commit includes several fixes to moving restraints; also added is support
for runtime integration of 2D and 3D PMFs from ABF.
Mostly changes to existing member functions, with few additions in classes not
directly accessible by LAMMPS. Also removed are calls to std::pow(), replaced
by a copy of MathSpecial::powint().
