Connect() with Unistore / Redux / etc

Right now you can't use `connect('foo')(MyAnimatedComponent)` since the connect wrapper receives the animation events instead of the animated component.

I realize this may not be easily fixable, since it's a very domain specific problem (trying to mix `connect()` with transition group).

In my case I re-published unistore with a "magic variable" to identify unistore wrappers, and re-published preact-transition-group with a check for that magic variable to decide which comopnent should have the animation enter/leave functions called. This is obviously a pretty hack solution, but maybe there is another way around this worth discussing?

For reference, you can see my test here. It ends up being a really clean app with animation support, since `connect()` and transition groups in this version will play nicely together.
