Added chapter descriptions
Chapter titles aren't just a 100% line-height now
Added pause/play to chapter title videos if they're not on screen
Take 10 off the value of parBot so that items are definitely off the screen when actions are taken
Removed the traditional slideshow variants
Don't autoplay chapter title video as we don't want to overload the users with sound and cpu usage
remove all instances of autoplay
Fix for layout of masthead video
Added necessary spans for image chapter title content
Removed all titles as they're not needed
Added a less intensive scroll function which waits until after the event to fire. It's not as smooth but it will do.
Fix for shutter slideshow video position
Slideshow full doesn't need padding.
Abstracted out some of the functions so it's easier to see where onScroll and deferred scroll functions should occur.
