Added modal functionality to occur when the user clicks 'Destroy'.
This is also an option to add when the user clicks 'Teardown'. ATM it seems a bit redundant, and if all of their infrastructure is torn down anyway, it doesn't really seem like a risky action that needs to be gated. If we feel differently, though, it will be a snap to implement with the new Modal component 😎
There are now basic dialogues displaying when there are no preview apps, or when destroy has been clicked.
Messages now pop up after clicking 'teardown' to report on the status of Lambda teardowns.
