Introduced 'Finalized' attribute in the NetCDF file

 - is set to 0 at beginning of run, and to 1 at the finalization.
 - field_transform.f90 checks for it being 1 at the beginning and waits for 60s, if it's still 0.
 - attribute 'percent completed' stores the progress of the calculation (is only updated once a strain dump is done, so slightly lagging behind)
PyAxi.py: Seismograms start at t=0 now

 - Just a very hacky fix to avoid timeshift in testing routines
Avoid output conversion crashes for very large files

 - or very small ones (with unnaturally high transfer rates)
Merge branch 'master' of https://github.com/geodynamics/axisem
Optimization of fieldtransform.sh

 - switched from CShell to Bash to allow exit on error
 - Not created on the fly in submit.csh to keep that tidied up ;)
More robustness of field_transform.F90

 - If progress attributes have not even been written, it continues anyway
make_netcdf.sh: Do not overwrite LD_LIBRARY_PATH

 - Some ifort configurations set this variable themselves. If overwritten by this script, shared libraries are not found anymore
Update NetCDF file to version 3

 - Error in mesh output: anisotropic parameter phi was written into 'mesh_mu'
 - Hooray for unit testing in the kerner
 - Makes all old files obsolete.

buffer needs to be large enough in case of many cpus

at least give a decent error instead of just segfaulting
adding a comment
more detailed error msg
in case of fluid core, sort all fluid elements by radius

to make sure that the domains are connected and every domain as maximum 8 neighbours
avoid file access if not necessary
multiply time step suggested by the mesher by an empirical factor

depending on the time scheme
adding attenuation switch to netcdf file

increasing file version, but should be backward compatible
removing some spam from output file
adding SEM stuff to netcdf file
adding sem stuff to field_transform, increasing file version

should be backward compatible, just adding some data
