Text style menu entry

[Jean-Pierre Chrétien]

Hello

After the review of the documentation to make clear the distinction between text 
properties and text styles, new subsection 3.5.7.1 refers to a non-existent 
"Text Style" menu entry. "Text properties" seems more appropriate, knowing the 
builtin styles can be found in the "Semantic Markup" column there. I intend to 
correct this, does it seem OK ?
