Changes to parameter names in the nodeOperatorSatelliteDestructionMassThreshold class

[abensonca]

Revision 7e0956 makes changes to the names of parameters used by the nodeOperatorSatelliteDestructionMassThreshold class. Specifically:

• massDestruction becomes massDestructionAbsolute;
• massDestructionFractional becomes massDestructionMassInfallFraction,
  and there is a new parameter massDestructionMassTreeFraction which sets a destruction threshold that is a fraction of the total mass of the merger tree.

As usual the ./scripts/aux/parametersMigrate.pl script can translate old parameter files to the new parameter names automatically.
