BumbleBee Quad mk2

I was so pleased with my first attempt [The BumbleBee Quad](http://www.thingiverse.com/thing:2279814), I decided to make some upgrades. I wanted to add the ability to lock the top on without using a rubber band. As part of that, I decided to make a battery holder as part of that. This is still a work in progress. While the battery compartment works well to hold the battery, it will still come out and sometimes come off on some of the more violent crashes. I need to improve it moving forward.
