"patch-needstranslation" changes the SpecialNeedsTranslation in that :Thanks,
instead of link to "Expression:", we have a link to the actual "DefinedMeaning:"
that needs to be translated.
"patch-classes" changes the way the classes are displayed when you want to
add a class to an element.
The current way displays in the first column the name of the classes
and in the second column, the collection to which the class belongs
(which is almost always "Omegawiki Community database")
I have changed it so that the second column now displays a definition of the class.
Note: "patch-classes" also includes additional documentation in the code,
that I am trying to add when I understand what a function does.
