Fix for bug #21042 (https://gna.org/bugs/?21042).

The docs/latex/fetch_docstrings.py now asks the graphics.fetch_icon() function for the relative path
to the icon rather than the absolute path.

The graphics.fetch_icon() function can now return either the absolute or relative path to the icon.

This is a partial solution for bug #21042 (https://gna.org/bugs/?21042).

Added a new user function to the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.

This is the chemical_shift.read user function which currently does not exist. Chemical shifts are
needed to interpret off-resonance R1rho data.

Updated the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test script for the new file names.

Changed the synthetic data file names for the TP02 dispersion model.

Created the relax script for the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.

More error message improvements for when peak intensity data cannot be found in a dispersion analysis.

Improved the error message for when peak intensity data cannot be found in a dispersion analysis.

This is to better aid the user to track down what they did wrong.
