Revert "[WIP] Multi-window"

This reverts commit 678ef640fedb93dcfaf00c3fd9a2ec4773e9f2a0.
[WIP] Multi-window

This is a big work in progress, which currently has some bugs,
but begins to look okay.

You can already multitask a little bit, by using the
app switcher and long-pressing an icon, then select "Add to
Split View".
Last window touched gets the key focus.

Still are some issues with rotation handling - touch an app
after rotation to make it relayout.

Enjoy :)

This has been a highly requested feature so I guess it's about time
we implement it :).
