[imp]Client side validation for menu type single article

[Erftralle]

Test instructions

• Go to Menu Manager: New Menu Item
• Enter a menu title
• Select Single article for Menu Item Type
• Do not select any article
• Click on Save or Save & Close

You will recognize:

• The system message container just displays the message Error without any hint to the field concerned
• The field label will not be coloured red
• If you select an article now the red colouring is not removed

After applaying the patch:

• The system message container now displays the additional message Invalid field: Select Article
• The field label will be coloured red
• After selecting an article the red colouring is removed now

If this amendment is agreed I would provide similar changes for the menu types Single contact and Single newsfeed. See also #6654 and #6761 dealing with the same problem.

The rendered msg:

This is B/C and I think it should be also applied to contact and newsfeed! Thanks @Erftralle

Thanks a lot for testing.

I have created pull requests #6888 and #6889 which apply the same changes to the client side validation of the menu item types Single Contact and Single News Feed.
