Title: Cancel any previous delayed hide requests and replace them with the current one

I'm using your excellent HUD class as a user browses a number of views, while showing an index position in the collection. My HUD is configured to hide after a couple of seconds of inactivity.

This small patch avoids the HUD disappearing and suddenly reappearing while this happens.
Any previous delayed hide requests are cancelled, and the new delay takes effect.
