Micah Tigley c784c7cf74 Bug 1680637 - Add a dialog manager for content prompts in TabDialogBox r=jaws,Gijs
The TabDialogBox will manage two separate SubDialog managers at the tab and content level. Dialogs managed at the tab level will always be on top of content ones and should always receive focus first when tab switching or refocusing the window.
