Spacing fixes for the GUI user function descriptions (for both the theory and practice).

The dauvergne_protocol sample script initial pipe name has been modified to include the pipe bundle.

The GUI now sends the pipe bundle name into the relax_fit and noe auto-analyses.

The relax_fit and noe auto-analyses now centre around the pipe bundle rather than data pipe name.

These now have the pipe_bundle argument.

Fix for the model-free about dialog - the fonts for the different titles can now be set.

The new font.roman_font_18 has been added, and the about dialog draw_title() method now takes the
alt_font arg for specifying an alternative font.

Fix for the model-free part of the relax controller.

This was broken by the change from the pipe name to pipe bundle for identifying the analysis. The
controller analysis_key() method was returning the pipe name rather than bundle name, causing the
matching to the status.auto_analysis object to fail. Hence the controller was not updating!

The about dialog now used the gui.fonts module.

This allows the fonts to scale to a decent size on Mac OS X, so that the text is readable.

Added a set of roman fonts to the gui.fonts module - this will be used by the about dialogs.

Font size improvements for Mac OS X.

The fonts are now roughly the same size as on GNU/Linux and MS Windows. An operating system
specific font scaling is now used, with the Mac OS X fonts each being increased by 2 pixels.

More fixes for the dauverge_protocol auto-analysis for the internal pipe name changes.
