U4-2962 - With the new editor name changes it doesn't clearly show you validation errors when you have an empty name

It also means that the "Saving..." message is displayed even when there are validation errors, it needs to check if the form is valid first and if not perhaps say "Validation errors" ?

Header displays an error indication, that a value is missing, added additional height to the element to ensure you can click it.

Hrm, definitely not seeing any error message, just a dotted red line and when you click on Publish/Save it still displays the message "Publishing..." or saving even though validation is invalid.

Something has happened to this name box again, there's now no failed validation indication at all - a message will need to be displayed there like we had before because the server might return a validation message for this field.

Actually, turns out that validation has been completely removed!

I've commented on this commit here: https://github.com/umbraco/Umbraco-CMS/commit/0f424d314f2a00796035781fb80b053937ab3325#commitcomment-4621471

I suggest that we revert back to use umb-content-name - it might need to be fixed up or whatever but the validation in there is absolutely necessary.
