Various fixes related to Ramsey with instruments
- Fix display of instrument termination value in
evaluate_steady_state.m
- Fix number of Lagrange multipliers in
evaluate_steady_state.m
- Provide dedicated
maxit
option for Ramsey - Add check for complex numbers in conditional steady state (prevents cryptic subsequent errors)
- Return with error if solution does not satisfy specified tolerance
- Suppress output unless explicitly requested (required for e.g. estimation, see #1173 (closed) )
