dislocation velocity output for each dislocation type (edge+,edge-,screw+,screw-)
...
for fcc constitutive_nonlocal_kinetics is called only once and the result is used for each dislocation type, for all other lattice structures we have one call for each dislocation type

Reworked kinetics. Now there is a universal law which can be used for both fcc and bcc (and probably even hcp). It mainly consists of an athermal forest cutting part , solid solution and peierls as thermally activated processes, and viscous glide. Therefore, lots of new parameters in the material.config. Not sure yet if the values make sense though.
...
Also renamed some of the old parameters.
Unknown constitutive output raises error.

dislocation stress does not add to stress field anymore, but is only available as constitutive output for purposes of postprocessing. instead, we now use a backstress term (which is added to the resolved shear stress) that depends on the gradient of excess density on the same slip system.

restructured algorithm: moved into loop to reallocate fields and replan FFTW in case resolution changes during runtime ==> regridding
...
introduced parameters for selective debugging of spectral code and partly introduced the advanced divergence calculation again which is controlled by debug.config
added switch in numerics to control divergence behavior (uncorrected and corrected by phenomenological factor)
added precision directive to all values I found

new outputs "accumulatedshear", "velocity_edge", and "velocity_screw" (the latter two replace the output "dislocationvelocity")

you can now switch of shear banding by seting sb_velocity to zero
stacking fault energy parameters are now read from material.config

* comments are now recognized by IO even when they do not appear at the beginning of the line
...
* no need for the zero entries in the material.config anymore

component type (random) asigns random orientation to an entire grain
