AMT Supervisor displays blank page when second command rec

[John Richard Procter]

In the supervisor, when the user searches for recordings and does reviews on recordings,
an animated gif will be displayed. All the clickable links and buttons on the screen will
be disabled. This will keep the supervisor from double clicking on links. When the loading
image disappears, the next screen is finished loading. This loading screen is also available
on the AQM reports screen.
