[1D] Added a new log level for saving intermediate solutions

Browse source 
Running Sim1D::solve with loglevel set to 7 or higher will now save the solution
after each attempted steady-state solution, after timestepping, and after
regridding to the file 'debug_sim1d.xml'. This can be useful for diagnosing
convergence issues with some problems.
