Add saving of parameter names to make loading of mh_mode-file compatible with mode_file option
Add info to dynamic and static file headers that auxiliary equations may be present
Cosmetic fixes to dyn_ramsey_static.m

Also makes sure that the check flag is returned and the steady state file always called if it exists. Otherwise, parameters might not be updated and NaN not detected.
Fix bug in dyn_ramsey_static.m with steady state file that resulted in incorrect steady state when running twice

The x returned by a steady state file includes Lagrange multipliers. When starting with 0 multipliers, the steady state of the multipliers is computed correctly. But when running it a second time like in a subsequent call to stoch_simul, the algorithm thinks that elements of xx are 0 which they aren't. As a result, it finds minus the multiplier as the solution, resulting in an output of 0 for all multipliers.
Test the result of steady state computation for correctness

- Checks correctness of steady state file
- Tests whether result of computation really is a steady state
- Also eliminates case that can never be reached
Add bunch of unit test checking the correctness of Ramsey computation with initval and steady state files

Improve computation of outer product gradient for univariate Kalman algorithms, by exploiting the larger number of individual densities computed during recursions (used in optimizer number 5).
