AUI-1409 - Make aui-scheduler week view accessible

Hi Marc,

I'm almost done with the scheduler, yay!  I've broken everything out into it's own branches that can be merged independently so they can easily be reviewed.  The only one that requires more base commits than the two you sent to eduardo (ed9e6b6 and 9483f33) is this one.  It requires the changes that I sent you for the day view as well because the week view extends the day view.

Please let me know if there are any issues.

Thanks!
