Widen Admin Security Page, Allow Column to Show full Content

The Administration > Security page has as roughly 800px table for the internal user list.  the columns in that user list are fixed and cannot be widened or sorted.  Since the name, and roles columns are long for some users they get truncated in the UI, this makes it difficult to see the full content.  Would like to see the full Roles so we can easily audit the roles assigned to a given user.

One option is to show the full content of the table without truncating and add a horizontal scroll bar (if needed)
