Tiles floating clients during expose view

Thanks to Falco I noticed that its cumbersome to have some floating
clients during the expose view of all clients. What do you do if the
client you want is below a floating client?

Well now we make everybody tile during expose, then restore their states
when leaving the Revelation tag.
