Introduce the option to send output scripts for single runs to the cluster (comparison scripts will follow later)

Subsequent runs: do not save the timestamp to cfg$results_folder in RData files that are stored on REMIND's main folder. These files might be used to restart subsequent runs by hand. In this case the timestamp would cause the script to stop because the results folder already exists.

Update realization files

Smoothed the introduction of a constraint on biomass. The constraint

update README.md and documentation in module 32_power

Move some declarations from the core to the modules

fix bug for starting compare scenarios

limits the share of traditional biomass taking the level of industrial
demand into account

Delete lusweave output files after generating runtime.pdf

vm_effGr and vm_damageFactor are declared in the modules 20_growth and 50_damages respectively.

turn on c_scaleEmiHistorical as default

Bugfix in start scripts (testOneRegi) and compareScenarios

add testOneRegi option to refactored start scripts

Corrections for start scripts

Refactoring start scripts: fix bug in sbatch command, remove scenario name from name of log.txt so the rs script can easily find it.

Documentation module 04_*

bugfix 0935e7ee due to 1st_gen biomass

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

- testOneRegi runs are useful for fast development iterations ("do these
  changes break the model, or does it still run"), so setting them up
  should be fast as well

- supplying the parameter "--testOneRegi" to start.R will ignore any
  scenario_config file provided and modify the default configuration to
  start a testOneRegi run in the directory output/testOneRegi with no
  output processing
- the old oneRegi.R script and oneRegi.cfg configuration are deleted

- existing output/testOneRegi directories are overwritten
