Slider for featured album on homepage

[Klikini]

Provides a new theme setting that takes the name of an album and displays it as a slider at the top of the homepage using lightSlider instead of listing it with the rest of the albums.

Very nice looking! I am going to leave @rprieto in charge of approving this one as it is his project. I made the previous theme w/ the exif info, and definitely like this direction.

I suppose I should hack away at some custom css to make my personal gallery look a bit nicer - love the dark twist on yours.

Just pushed a quick change that works around an issue in lightSlider.

Update: That issue seems nastier than I first thought; several workarounds all failed. I might try finding a different slider library. If you still want to merge this, the worst that happens is that the slider itself doesn't appear (try refreshing the demo a few times), but the thumbnails do (and they still scroll correctly), so it's not horrible. Either way, I understand, and once exams are done, I will try to figure it out.

@amcolash Thanks 😄 I'm coming from Zenphoto, where I always used the default dark theme, so it just made me feel more comfortable to change the color variables here. Now I just need to figure out how to allow linking to individual photos and I'm all set!

Since this still appears to be an issue with LightSlider and I think it's best to keep using a plugin compatible with LightGallery, I just added some CSS rules to force a constant slider height (defaults to 400px, but can be changed with @slider-height).

If this is still a welcome addition, I think that fixes it (see if you can break my demo, I haven't been able to yet).

Hi @Klikini, I'm not sure why I'm only seeing your PR now. It's a great feature, thanks for building it!
