EDGE-T scenarios update; EDGE-T supports non-fuel divided by model type and differentiated learning.

change version of gdx being used for NDC target calculation (now input_bau.gdx) so that correct NDC targets are also calculated for non-SSP2 pathways

- added documentation to the output script.
- updated the multi-comparison-matrix.
- updated the prefix used for coupled runs.
- correctly handle the number of cores to be used in parallel.

Add .Rprofile to the list of files that are copied into the results folder *before* prepare_and_run is called.

gdx neutral: clean scenarios in scenario_config_coupled_SSPSDP.csv and compareScenarios.R, add start and end time (of the job not of GAMS) to runstatistics.

Script now returns after saving RDS files when in reporting mode.

- remove *explicit* flags for vintages and learning, essentially
switching those to TRUE by default.
- save and load RDS files to a subfolder in the output directory to
not clutter the output dir too much.
- add and group all RDS file save that are related to reporting.
