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)

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.

introduced possibility so specify deformation gradient aim at end of load case, rate will be calculated using difference between start of load case and aim. Needed for cyclic loading.
...
Use keyword "f" for this behavior, don't use it as short name for freq any more!

divergence_correction for basic solver variants has now 3 possibilities:
...
0: uncorrected, slope per sidelength (physical dimension) e = res/dim
1: corrected by sidelength, slope per unitlength e = res/1
2: corrected such that distance between FPs e = 1
alway regarding the medium length of x,y,z direction

7b87987751
introduced option for regridding to numerics.f90, working as follows:
...
first cut back is tried if material point model oder BVP solver does not converge.
If no regridding is enabled after max cut back, in case of non-converged material point the simulation stops and in case of non-converged BVP solver it continues.
set regridMode to 2 to enable regridding if BVP solver OR materialPoint model do not converge,
set regridMode to 1 to enable regridding if materialPoint model do not converge, non-converged BVP solver will be ignored as in the standard case.
For regridding, the load case need to have a restart freq set.
enabled restarting for Basic PETSc variant

some small changes in including PETSc *.h90 files to prevent warnings.

It seems that a bug in old gfortran 4.5.0 causes the problems, at least with 4.7.3 it seems to work after fixing the bugs in IO.f90
