  generators: Implement beam file with inclinations

Implement using another format for the beam file, which contains the
beam inclination and the absulute beam momentum instead of the
3-momentum of the beam particle.
In addition, the full measurement correlation among the vertex x/y
postion and the beam inclination is taken into acount to smear out the
single events with a multivariant gaussian.

  generators: Implement takeZpositionFromData flag for beam file

If the takeZpositionFromData flag is true, the Z-positions of the
vertices are not drawn randomly according to the target definition, but
are directly taken from the beam file.

  -----------
  generators: Correct momentum resolution for beam file

The momenta in the beam file are afflicted with resolution effects.
Assuming Gaussian PDF's for the resolution and intrinsic beam PDF, one
can correct for this effect by randomly drawing the truth beam energy of
each event in the beam file according to the corresponding PDF.

- improved parameters
