fixed bug in initialization when reading in material.config.
...
Fortran does not short-circuit, e.g. (if a>0 .and. b(a) ==c) might cause an out-of-bounds error when a=-1 it'll try to access b(-1)!

slight change in flux formulation: no flux to neighbor, not only if there is a sign change in the velocity, but also if the neighboring velocity is exactly zero

improved accuracy of "accumulated shear": now added as a state variable, which facilitates integration (dotstate=shearrate); needs absolute tolerance value for state integration in material.config

changed all remaining routines to fortran-fast arrays (geometry reconstruction etc.)
...
changed all remaining routines in f2py to more clever determination of array size (requires f2py >= 2.0)
enabled 3D visualize to work with odd resolution by switching to linear reconstruction
PLEASE NOTE: Redefinition of routines for f2py might cause trouble -> DELETE DAMASK_ROOT/lib/damask/core.so in this case
further changes: added pure statement where possible, polished, unified use of "Q" for "Quaternion" and reordered math to have similar routines together
