Scheduler Commit -- work yet to do as far as running of schedules. Generally a simple schedule should startup and work. Some of the controls on the status dialog are not working well or at all yet.
Scheduler, if enabled would crash Vixen if no show was setup. Oops.
Check for invalid elements effects. Caused by heavy updating of the element list (I think)
Cleanup Nutcracker useless timer
Add error checking to Chase effect for null nodes and invalid node index
Add error checking to Pulse, Spin and Twinkle
Check for null nodes -- caused by heavy editing of the element tree. Error prevented sequences from being played.
Attempt to get scheduler running better.
Update folder references
Merge branch 'Scheduler' of https://github.com/derekbackus/vixen into Scheduler
