FormDependency for ReadOnly status and for new record.

[paladin80]

It will be nice to have FormDependency rules to change fields to ReadOnly and back.

Also user may want to have a simplified form view when creating a new record. FormDependency would be great instrument for this case, if it could track the "new record" status.

setReadOnly and setNotReadOnly already exist

hide and show work with panels or fields. However by default, custom panels don't have a name property.

frontend/client/src/views/record/base.js
            switch (action) {
                case 'hide':
...
                case 'show':
...
                case 'setRequired':
...
                case 'setNotRequired':
...
                case 'setReadOnly':
...
                case 'setNotReadOnly':
...
        }

BTW In future I want to add additional more flexible FormDependency syntax.
