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!
but this does hide the ui of lightbox
hot the whole lightbox
hidden might confusingly mean that this does hide the whole thing

this could be named hidden footer and hidden header
maybe I should use two classes for that?
