fixed scrolling lists with the mousewheel for some X11 windowmanagers.

Browse Source 
some WMs not only send 'crossing' events when really moving from one
window to another, but also when mousewheeling.
distinguishing those events 'mode' property fixed this.

brecht++ for figuring out the details.

we only do moves when the crossing mode is 'normal'
(really crossing between windows) since some windowmanagers
also send grab/ungrab crossings for mousewheel events.
