Tell a person when their column layout was not saved

[tylercschneider]

One Sentence Summary

A person who changes a table's columns is now told when that change was not saved.

ACs Covered

• When the server answers the save with an error, the Columns menu shows a message saying the change was not saved.
• When the save cannot reach the server, the Columns menu shows the same message.
• After a failed save, the menu's boxes and column order go back to what the table is showing.
• After a failed save, the page does not reload.

Decision Log

Where does the message about a change that was not saved come from?

The Columns menu arrives from the server with the message in it, kept hidden until a save fails, instead of the browser creating the message after a failure.
