Added the closeOnScroll option.

[chrismeyers]

This option prevents the gallery from closing upon scrolling. When this option is set to false, background scrolling is disabled until the gallery is closed.

This feature was primarily implemented to allow zooming/panning on mobile. When coupled with some overriding CSS like this:

.fullscreen-v-img {
  touch-action: pinch-zoom pan-x !important;
}

you'll be able to zoom and pan without the gallery closing.

Hi @chrismeyers, thank you very much for the contribution!
Unfortunately, I'm unavailable to work on the project now.

@anandkulkarni
Maybe it's possible for you to allocate some developers for this project? People are making contributions and it would be cool to at least merge changes (and probably write tests, so merging changes would be less painful in future).

Thanks.

Hi @crowdbotics-apps,

Could you please let us know when this PR is merged or when this functionality is integrated? It is really useful to disable this option if we want.

Thanks in advance.
