Comment 5 for bug 1812414

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/collab/sleary/lp1812414-logout-shortcut

Updated branch, with help from Galen and Mike on figuring out that we needed to change from a directive to a component to make AccessKeys show a dialog.

This makes it possible for other keyboard shortcuts to implement confirmations before the requested action is taken.
