Persist Timer manager between scenes

[Petethegoat]

In my current project I use timers to drive some nice presentation lerps and stuff while async loading the next scene.

This totally broke immediately because timers are cancelled on scene change, so I marked the initial manager as DontDestroyOnLoad and it works fine.
I think this is pretty useful functionality, so how would you feel about a pull req that implements this properly, with the manager manually cancelling all timers on scene changes, unless they're specifically marked to persist?
