We improve the readonly mode in several ways:
- instead of displaying ids for relational fields, we display the
associated names.
- instead of displaying values for selection fields, we display the
associated labels.
- quotes around strings are not displayed by default. They are if
there is some ambiguity: the presence of a value of another type
like 0, false or an expression makes necessary to put them.
