Created a base data pipe for Flemming Hansen's truncated CPMG data for testing out missing data.

The :4 spin is missing just a few data points, whereas the :71 spin is missing all 800 MHz data.

Synchronised the test_suite/shared_data/dispersion/Hansen/relax_disp.py with the sample script.

This script now matches very closely with the sample_scripts/relax_disp/cpmg_analysis.py sample
script. This is for sample script debugging purposes.

The os.sep variable is now used by the cpmg_analysis.py dispersion sample script.

Docstring improvement for the test_suite/shared_data/dispersion/r1rho_off_res_tp02/R1rho_analysis.py script.

Added the DATA_PATH variable to the cpmg_analysis.py dispersion sample script.

This allows the user to more easily specify a different directory for the files.

All of the relaxation dispersion auto-analysis options are now exposed by the sample scripts.

This included the pre_run_dir argument for specifying a directory of results from a non-clustered
analysis and the flag for running MC simulations for all models.

Fix for a number of PNG files for NESSY and Bruker icons for broken IDAT entries.

This problem was identified by Justin Lecher <jlec att gentoo doot org> in the post
http://article.gmane.org/gmane.science.nmr.relax.devel/4750 (Message-ID:
<5298572C.5010409@...>), or in the threaded view
http://thread.gmane.org/gmane.science.nmr.relax.announce/46/focus=4750.

As a result those icons are missing in the GUI. This was fixed using the pngcrush tool.

Bug fixes for the non-functional R1rho_analysis.py relaxation dispersion sample script.

This script was horribly broken, but it should now work. It can even be executed from the base
relax directory or from within the sample_scripts/relax_disp/ directory and perform the full
analysis (assuming write access to the relax source directory).

Update for a comment in the test R1rho dispersion sample script.

Setup for testing the sample_scripts/relax_disp/R1rho_analysis.py sample script.

The script was copied into the test_suite/shared_data/dispersion/r1rho_off_res_tp02/ data directory
where it will be tested on real data. The 'fake_sequence.in' and 'unresolved' files have been
created to allow the script to run. And the script itself has been heavily debugged.
