Include job_id in all output files

[jjohnston203]

(Morpho 1 enhancement)

As discussed in pull request #68, the --job_id argument is currently only appended to the output of the file containing the stan results. We want to update morpho so the job id is appended to all output files. This means that every preprocessing, postprocessing, and plotting method that can output files must be edited.

The first step is to pass the job_id to all methods:

• Edit morpho to place the job_id in every preprocessing dictionary, every postprocessing dictionary, and every plot dictionary, with the key 'job_id'
• Create a method to append job_id at the appropriate place in a filename (ie before the file extension)

The method to place job_id in the filename must then be added to all of the following methods:

• preprocessing.resampling.bootstrapping()
• postprocessing.data_reducer.data_reducer()
• postprocessing.general_data_reducer.create_output_file()
• plot.histo.histo()
• plot.histo.spectra()
• plot.histo._save_histo()
• plot.histo.aposteriori_distribution()
• plot.histo.correlation_factors()
• plot.neutrino_params.plot_neutrino_masses()
• plot.neutrino_params.plot_mass_params()
• plot.neutrino_params.plot_mixing_params()
• plot.neutrino_params.plot_contours()
• plot.spectra.spectra()
• plot.timeseries.timeseries()
