Added a LaTeX label to the J(w) mapping chapter.

Added the other consistency testing references to the citation chapter of the manual.

Added the Fushman et al., 1998 reference.

Fix for the Farrow et al., 1995 DOI number.

Changed the order of the Rx curve-fitting and NOE chapters in the relax manual.

This is because the NOE chapter references passages from the Rx curve-fitting chapter, so it's more
logical to have the Rx curve-fitting chapter first.

Clean up of a paragraph of the data model chapter of the user manual.

Improved the consistency on the user manual by using the new LaTeX commands.

These changes are throughout the manual and affect all the text of user functions, menu items,
prompt examples, GUI elements, files, directories, etc.

Removed some '()' text from the end of the user functions in the user function documentation.

Added some more LaTeX functions for formatting consistency.

Defined a new set of LaTeX commands for prompt/script/GUI strings and elements for the user manual.

These will be used to regularize the text throughout the manual, as this is currently quite mixed
up.
