bugfix 0935e7ee, reintroduced an if/else condition for a bound on biomass and renamed c_1stgen_phaseout into cm_1stgen_phaseout

The code should now run. Some namechanges had to be corrected/reversed. These module additions do not affect the results. Further improvements will be commited at a later date.

This is part of a larger refactoring effort of the remind core. Here, code related to the trade of permits and primary energy carriers is moved from the core to the new module. Some renaming is required. For now only one module realization exists, 'standard', which corresponds exactly to what was in the core before. The results are not effected!

This is part of the larger refactoing of the core.

move scripts for magicc into the folder core/magicc, delete outdated script performance_test.R, integrate script submit_compare.cmd into multiComparison.R

Refactoring: -start scripts (part 5): renamed submit_run(cfg) into submit.R(cfg), deleted conopt files

Refactoring: - part 2: restructure start scripts (try to minimize workload for the login node on the cluster when starting a REMIND run by moving code into scripts that are included in the slurm job)

Refactoring: - restructure start scripts (try to minimize workload for the login node on the cluster when starting a REMIND run by moving code into scripts that are included in the slurm job)

Refactoring - delete realization linadjust of module 45_carbonprice, general code cleaning (mainly start_functions.R)

             - remove old_cluster

These are mainly naming inconsitencies in the welfare module.

This is part of a larger refactoring effort of the remind core.
Here, code related to the social welfare functions has been moved
from the core to the new module. Some renaming was required. For
now, only one module realization exists, 'utilitarian', which
corresponds one to one to what was in the core before. This
refactoring exercises has no effect on the results!
