Create a BigRedButton struct, like CloseButton

Browse Source 
The `BigRedButton` should be a real struct and component so that I can
query for it later.

I'm following the same API pattern as the `CloseButton` struct, in that
there is a spawner using the `Commands` (or `ChildSpawnerCommands`) and
the observer functions are static methods.
