nonSchmidProjection was reset to zero each time during instance loop in init, so entries from previous instances got lost; fixed that

in kinetics: non schmid stresses only influence peierls mechanism, but not solid solution hardening; as a result the derivative of the velocity with respect to the resolved stress has to be split into a Schmid and a non-Schmid part

fixed bug that occured under marc (and abaqus?) with openmp:
...
"lastLovl" (for marc) and "lastStep" (for abaqus) have to be global module variables in FEsolving.f90 instead of local variables in the respective DAMASK_* files; otherwise they are initialized with zero each time hypela2/umat is called.

nonSchmid tensors according to Koester,Ma,Hartmaier,2012.
extended lattice_Sslip with non-Schmid tensors (the full non-symmetric tensors are required for the tangent and cannot be retrieved from the symmetrized Mandel notation)

plain mode (no ping pong) now seems to work for marc, further testing needed

regular sequence of computation modes is
inc 0: 1,1,1,…
inc 1: 0,0,0,…
7,1,1,…
0,0,0,…
1,1,1,…

after a cutback the computation modes follow as
inc 5: 8,0,0,…
1,1,1,…
0,0,0,…
1,1,1,…

removed variable lastMode from FE_solving, used to be used for detection of first call after ping pong; now this is done by checking for a change in the lovl (macro) or a change in the calculation step (abaqus)

Changed order of blocks associated with different tasks:
...
backup jacobian
restore jacobian
age results
collect
calc
This becomes important if multiple tasks are requested by one call to CPFEM_general. In plain mode this could, e.g., be
1) backup jaco, 2) age results, 3) calc

changes on convergence tolerances of AL and Polarisation, switched back to immediate correction of stress bc but only when last two average stresses are close to each other (cosine decay)

03d8f14a98
introduced dynamics for high strain rate simulations. so far only works for materials with homogeneous density. the density is read in as an optional argument in the load file using the keyword 'den' or 'density'. if density > 0 then inertial terms are added to the stress equilibrium. an implicit euler time discretisation is used to calculate the inertial terms.
...
dynamic problems are length scale dependent so make sure the geometry size is meaningful (1 m^3 or N m^3 for example is too big for a RVE!).
not specifying a density (density = 0) will perform a quasi static simulation as before.

decoupled compatibility/equilibrium calculation from stress BC correction. needs more iteration for mildly contrasted materials, but there the basic scheme is better suited anyway. but now converges better for highly contrasted VEs
