Automatic add width on the flipsnap container

[andycall]

I found the width of the flipsnap container is setting with CSS but not JS,
it's not a good way if I am not sure about total image amount and without the width settings in my css file, the flipsnap is going to collapse!

Exactly, flipsnap don't set width automatically. You need to set manually. See the demo below.
