Change for norm_type variable in the relaxation exponential curve-fitting auto-analysis.

This is now set to 'last', not only for the saturation recovery, but now also for the inversion
recovery experiment types. This ensures that the normalisation point is the steady state
magnetisation peak intensity.

The relaxation exponential curve-fitting auto-analysis now sets the normalisation type.

This is for the new grace.write user function. If the model for all spins is set to 'sat', then the
norm_type will be set to 'last'. This allows for reasonable normalised curves for the saturation
recovery R1 experiment types.

The new grace.write user function norm_type argument has been activated.

The argument is now passed from pipe_control.grace.write into the write_xy_data() function of the
lib.software.grace module, and is used to select which point to use for the normalisation.

The relax_fit_saturation_recovery.py system test script now sets the norm_type argument.

This is for testing out this new option for the grace.write user function.

Added the norm_type argument to the grace.write user function.

This is in response to http://thread.gmane.org/gmane.science.nmr.relax.devel/7392/focus=7438.

This norm_type argument can either be 'first' or 'last' to allow different points of the plot to be
the normalisation factor. The default of 'first' preserves the old behaviour of first point
normalisation.

Parsed the dic, udic, data from pipe_control into backend of contour_plot for nmrglue.
