remove :timedout from the session hash (https://github.com/plataformatec...

I use devise in a project and just activated the timeout functionality. 
Since devise renders a :timedout => true into the flash Hash for some reason, this true value is rendered into the frontend. My hack just removes this key from the :timedout Hash.

There ist certainly a better solution for this, but it works well for my project and it might for others too :-)
