Events Enhancements`

[cwhittl]

I wasn't able to get change or ready working after digging around a bit I ended up with this

Changes:

• Added the ability to use ready and change
• Updated event list to what is available from latest Flickity
• Added ability to pass events as an object instead of adding them one at a time
• Updated readme with additional info on events
• Misc cleanup

Thank you for such an awesome addon!

Sorry for all the commits, I sorta got in and had to go a little hard core than I thought.
