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.

Added sectioning printouts for the relaxation dispersion auto-analysis.

This simply tells the user which part of the protocol is currently being performed.

Another fix for sample_scripts/relax_disp/R1rho_analysis.py to match the previous commit (r21701).

The problem was also at the top of the list.

Fix for the sample_scripts/relax_disp/R1rho_analysis.py sample script.

The problem was some extra commas which should not have been there.

Added many small details to the release checklist document.

This is for the formatting and editing of the CHANGES file, which is used for the release
announcements. Some additional details about the API documentation at http://www.nmr-relax.com/api
have been added too.

Small improvement for the devel_scripts/log_converter.py script for detecting commit boundaries.
