AlloyUI.com - Example - Scheduler.  Add 400 to nav z-index, fixes Scheduler display issue.

Hey Marc.  When I run git diff --name-status scheduler upstream/master the only changes I get between this branch and master are the example/scheduler files, and the newly added changes to website/css which push up the z-index.  Let me know if you see toggler or anything else weird in the diffs.  Thanks
