Set hierarchy constraints as default in Millepede

[mschrode]

This sets back the default way constraints are treated in Millepede to using hierarchy constraints, and reverts the temporary changes introduced with #6254. Previous problems were found to be due to numerical effects in pede. These are solved in >=rev137, which uses 'elimination' instead of lagrangian multipliers.
