enhancement: allow author window's listview to be sorted alphabetically by author column

[thewireguy@…]

The default sort order of the Authors Window's listview control is by the # Objects column.
It would be nice to also be able to sort the information alphabetically by the Author column.

usecase: I am a HOT contributor, and need to find the objects created by a specific author. There may be hundreds of objects in my task, and dozens of authors. Having the list displayed alphabetically would enable me to scan quickly without missing the author.

implementation: respond to a click event on either the Author or # Objects column header. Would sort clicked column ascending.
