As per discussion on gnucash-devel, move detailed content on the user interface from Help to Guide. Content from Chapter 3 of the Help will be merged into Chapter 2.3 of the Guide. Once text has been merged into the Guide, content from Help will be significantly reduced.
With a long delay I have merged this a second time, this time after restructuring the commits for the benefit of our translators. Thanks for your work and sorry for the long wait.
This have been commits 755d33c ... dd33457.
