Comment 2 for bug 1812866

This adds a new column called Item Alerts to the copy buckets grid (regular grid and pending grid) that displays the 'note' for all alerts that are attached to that item.

(The brackets are a side effect of the fact that an item can have multiple alerts and I'm not sure how to make that prettier, but at least the data available.)
