GUI: Alarm perspective button flashing when shortcut used

[AdrianPotter]

• Open the client
• Wait until alarms appear. The alarm perspective button will flash
• Open the alarms perspective with shift+alt+a
• The button will keep flashing

This is different from if you mouse click on the button. I expect the same is true of the IOC log button.

I started looking at this on a stand-down day, I'll note what I found here and put this ticket back into the backlog:

The issue here is that the logic to tell whether the button should flash or stay steady is in the UI layer (AlarmButtonViewModel), whereas the keyboard shortcut entirely bypasses the UI layer and switches the underlying perspective.

I think a better approach would be for the alarm model to listen for a perspective switch event (I believe you can subscribe to these events through one of the eclipse APIs) and then do the flashing/steady state logic in the model or possibly view model.
