Updated analysis.py for perp. conductivity
Corrected error in xmpar.py
Added possibility of cond. band. magn. input
Corrected input/output interchanging in euorun.py
More flexible mpirun command
Added possibility of changing email address
Better error management for faulty input folder
Updated system parameter for full RKKY
Added cleanning scripts
Inverted overwrite flag in getcond.py
Introduced long range coupling systems

In addition it is now possible to specify the system type to use
as an input from the database. Hereby it for example possible to
use EuGdO runs as an input for EuGdO-LR runs.

Moreover there is a new help message showing all system types in
the run.py routine.
More flexible input selection

Restructured the 'add_input' routine in database.py to gain more
flexibility for input selection. Now it's possible to
1.) choose a different system type as an input
2.) select which input should be prefered, local or remote, by
    new keywords for the source variable 'local-remote' and
    'remote-local'
and
3.) in the default case the input source with the higher
    temperature if prefered.
More flexible archiving of database results

Now it is possible to archive a single dataset. This dataset is
either specified by values e.g. "EuGdO 0.01" or by it's orgin
path. The latter version is used inside the euorun routine for
updating the database directly after a successful run.
