HBX-3166: Same usage order of reveng files and strategy for all tools

[fanste]

New logic is based (with minor optimizations) on the order of the ANT implementation:

• if a delegate is given, try to find a constructor with a RevengStrategy argument. If not found, try to use a no-args constructor and print a warning.
• if no delegate is given, try to use a no-args constructor. If not found, try to find a constructor with a RevengStrategy argument and provide a DefaultStrategy.
• If a revengFile is provided the strategy provided by the OverrideRepository is used as a delegate.
