Implement rate limiting toasts.

We rate limit showing toasts on a per package basis. Each time the app
hits the limit, any further toast attempted to be shown will be
discarded. Specific rate limits are designed in a way such that if the
app continuously posts toasts, the period for which it will be blocked
from posting gradually increases each time it hits the limit.
