Added the ability to skip the animations in playbacks and storyboards.

We can now skip the entire animation of playbacks by having the user
select an option in the speed control to ‘Skip Animation’. In a normal
playback this makes the tool step to the very end. In a storyboard this
makes the tool skip to the next event that has a comment associated
with it.
Renamed array with comment event indexes

Renamed an array in the global playback object that holds the index of
events in orderOfEvents that have events associated with them
Updated gitignore for Intellij
Add better toggler for animations to the command area.

This also did a small amount of cleanup on existing code. It should
probably have been two commits.
