- Removed the extensions of the external libraries in the test files.

ROOT is anyway checking multiple extensions for dynamic libraries, therefore leaving them out yields platform-independent msr files.

- Minor changes in libTFitPofB

- Added a user function for Uemura's ZF/LF dynamical spin-glass relaxation function
  see, e.g. Y.J. Uemura et al., Phys. Rev. B 31, 546-563 (1985)
  or Y.J. Uemura, Hyperfine Interact. 8, 739 (1981)

  This yields an overall Lorentzian field distribution with motional narrowing.
  However, the present implementation is at best some design study:
  The Lorentzian distribution of width "a" is modeled by Gaussian distributions of widths "sigma" from 0 to infinity.
  Some "resonable cut-offs" would be: 0.1*a < sigma < 10000*a
  Due to finite memory and computing power, in the present version these cut-offs are: 0.1*a < sigma < 40*a
  This yields depolarization functions overall similar to those in Uemura's articles.
  However, due to the low cut-off the first derivative of the depolarization function is zero in the limit t->0
  (what should not be the case for a true Lorentzan).
  Furthermore, the calculation is rather slow and the resulting functions should only be regarded as crude approximations.
  Therefore, at the moment this is far from being of practical use in analyzing experimental data.
