extend link field to optionally select foreign field

[hi-ko]

By now a link fields (link, linkMultiple, linkParent) show hard coded the "name" field of the referenced entity. Sometimes the name field may not be very helpful and should be replaced by a different field (e.g. the case number instead of the case name).

Example config using an optional field attribute to show e.g. field "number" instead of "name":

"fields" : {
    "caseTest" : {
        "type" : "link",
        "field" : "number"
    }
},
"links" : {
    "caseTest" : {
        "type" : "belongsTo",
        "foreign" : "tasksTest",
        "entity" : "Case"
    }
}

For belongsTo relations will be added in 4.6.0.

Paremeters foreignName to specify custom field and noForeignName to skip name field creation.

noForeignName is this still available as parameter. Couldn't find anything on the schema.
