Provide an opportunity for including conference-specific CSS

Browse source 
There is currently no top-level selector for views that is conference-specific,
so all conferences on one OSEM instance end up sharing all the same CSS.

In order to allow individual conferences to have unique CSS, a class for the
current conference is applied to the <body> tag, and an scss template provided with
an example of conference-specific CSS.
