Fix duplicate solutions, overflow in maxsols and improve symmetry reduction for H48.

This commit fixes two bugs:
  - A bug that caused duplicates solutions for symmetric scrambles.
  - An overflow in the maxsols parameter for the H48 solver, which
    caused it to find much fewer solutions than existed.

Moreover, the H48 solvers has been improved by reducing by symmetry not
only from the starting position, but also up to the first 4 moves.
