Fix job subfolder creation
Fix job subfolder creation

Create 'solver' folder in RMG.initialize() rather than
only when saveSimulationProfiles is on, because the solver
folder is also necessary for uncertainties.

No longer create the species_edge subfolder.  All species
images get saved in the species subfolder, so the
the species_edge folder is extraneous
