[Untested] Errors per field directive

Finds ng-model which matches the field (or fake-ng-model)
Looks for a parent with class row (or fake-row)
Appends error message after this parent

Directive appends methods showErrors and removeErrors to the shared object

```html
<form autoerror="autoErrorSharedObject">
```
```js
$scope.autoErrorSharedObject= {};
$scope.autoErrorSharedObject.showErrors(reason.data);
$scope.autoErrorSharedObject.removeErrors();
```
