Starts implementing Ticket 216. Most plotting and figure is now controlled by the functions dyn_figure and dyn_saveas, allowing for option_.nodisplay to suppress the displaying of figures and using options_.graph_format to control the format of saved figures.

nocheck to 'check' in test fs2000/fs2000a as there is a unit root and
the user provided _steadystate.m doesn't solve the static equations

them with setting info=1. The error messages should be managed by a
calling function

- Adds new algorithms to solve Lyapunov equations: Doubling algorithm and Square root solver. Their respective names are "doubling" and "square_root_solver".
- Adds the tolerance criteria for the iterative solvers (sylvester_fixed_point_tol, lyapunov_fixed_point_tol and lyapunov_doubling_tol)
- Updates the reference manual
