Allow targeting of non-body elements

[dabernathy89]

This is my first time contributing to a project, so forgive me if I'm going about this incorrectly. I liked your plugin, but I really only needed to run the slideshow on my header. I made some changes to the code to allow it to use a selector other than 'body', although body remains the default.

Thanks for your contribution.
I will check that as soon as possible. Be patient I'm really overbooked currently.
Thanks again!

Hey dabernathy89, this is just to say that I took a look at the code and think you will need to add a new var of $bgTarget = $() & set it in init() rather than using options.bgtarget throughout. options will not be defined in some of the methods.

[dabernathy89]

I did end up passing options to some of the methods that didn't have it previously. You think it'd be better to avoid that? With your suggestion, how would the user set the target?

[wiseguydigital]

Personally I would add it to the class config and set the value in init(). By adding it as an option to say overlay() you are hinting that the overlay could be set on a separate element to the main vegas element. I think you want one master target element and that's it. What do you reckon?

Hi there ! Thanks for contributing.

To keep the jQuery convention, it would be great to have a $(elm).vegas(options) to apply vegas to any element.

I have opened a pull request with the jQuery wrapper style: #23

Nice! Better solution than mine.
