Removes curvature tolerance from solver setup

[jmartfrut]

Removes the curvature tolerance (cuvtol) from the Newton_RaphsonSolver constructor and SolverTolerances struct. This value is not needed on construction.

Also hardcodes the curvature stopping criterion to 1e-5, which was the default, as a temporary measure to restore functionality.
