Revert "place child clients above fullscreen clients"

This does not work as intended. Lets revert it temporarily and add it back
after the release.

This reverts commit 298949bbc4eae8cedb9cdd11cfc9ebd139ac5d5f.

Fix applybounds

Applybounds doesn't move client when it overlays
only with border with monitor to the right.

Apparently, c->geom.width already includes the border
as well.

feat: focus empty monitor when clicked
