Hg 89 port lightbox

send action to ApplicationRoute
{{action 'openLightBox' 'light-box'}}
or
{{action 'closeLightBox'}}

to open close light box 
this should allow us to use subclasses for special light boxes
ie. 
{{action 'openLightBox' 'media-light-box' 4}}
to open 4th image in media light box
and this is what I am going to work next!
I am not a fan of selectors like 
```css
.lightbox-footer .footer-expanded {}
```
when
```css
.footer-expanded {}
```
is enough
