Make the engine capable to process HAZARD and HAZARD+RISK jobs

[Andrea Cerisara]

The engine must support the processing of HAZARD (only) and HAZARD + RISK jobs.

[Andrea Cerisara (acerisara)]

As agreed with Damiano, to trigger just the hazard computation a user should comment or delete the risk subsection (the section definition itself is enough).

[Andrea Cerisara (acerisara)]

I just found the engine already supports this feature. I was able to run just the hazard subsystem, by:

* setting the --include_defaults flag to false (via command line)
* commenting out the [RISK] subsection in my configuration file

That's good news :)

I don't know about you guys, but this is kind an obscure method for running hazard-only calculations. I think this should be much more explicit (command line switch, maybe?).

[Andrea Cerisara (acerisara)]

Damiano asked to run just hazard computations by commenting out the risk subsection in the configuration file. The --include_defaults is necessary because the engine merges the configuration with a default (risk enabled) configuration file, but IIRC we agreed to remove this unused feature sooner or later.
