Adapt script to gammalib-00-08-00 version.

When releasing ctools-00-07-00 we forgot to update the script.
Make effective area histogram rebinning optional.
CTA dummy reponse now installs in share/caldb/data/cta/dummy/.

The default CALDB data structure is data/<mission>[/<instrument>]. This structure is now respected.
Add database for DESY Prod2 files.
Update for Prod2 and add obsid to index file for selection.
Add energy dispersion information to CIF file.
Implement King profile PSF, Prod1 and test IRF production.
Adapt to new GCaldb interface.

A new logic has been implemented concerning the caldb parameter. If the name specified by caldb is a directory, the directory is set as the root directory of the calibration database. The file specified by irf must then be a file provided within this root directory.

If the name is not a directory it is used as the mission name that is used to build the calibration directory path. The irf is then the response name.
Calibration database parameters are still automatic.

We don't want to hide these parameters but parse for the instrument.
Update
Update version numbers
Add edisp parameter to ctobssim
Changed GCaldb::dir() to GCaldb::rootdir().
Merge remote-tracking branch 'cdeil/action_1109' into integration
By default, do not apply energy dispersion.
Adapt for handling energy dispersion.

True photons are now drawn over a sufficiently large energy band so that when dispersed the selected energy range is correctly filled.
Adapt for energy dispersion handling
Update parameter files.
Add energy dispersion handling.

The edisp parameter now allows to switch on or off the handling of energy dispersion. By default, energy dispersion is switched off.
Update after inclusing of energy dispersion handling.
