MIE-1536 - Custom template.

#### Changelog:
Only mobile (phone form factor). The badge's picture and its description are shown inline  at Followers and Following containers.

#### New:
     You can pass an optional parameter streamOptions on activity stream config so that these parameters can be restored from its handlebars model.


Where is `streamType` configured? Also, what are the different types of streams? Will we be curating and managing many different types of streams? I do not think so. I think it makes more sense to be straightforward about what we hope to accomplish with this configuration and name the option `invert` or `inverted`. This is more generic and useful.
