[reledit] reload support for relations

[reledit] landing zone useful only for relations; cleanup

[reledit] try to be smart at getting a good default vid for relations, factor computing cardinality from reledit and formfields

[reledit] do not strip values (we should not make judgements about field contents ...)

[reledit] have a link-free landing zone for mouse-clicks (closes #343544)

[reledit] small cleanup and add escape param to control xml_escapability of the value, also rename vid arg which clashes with entity.view(...) args

[reledit] use guess_field, thus fixing select widget lacking a multiple attr. in case of * cardinality

[reledit] onsubmit event is not common to both cases, move from class
