WIP: Brand types

/cc @commuterjoy @wheresrhys @matthew-andrews 

Just to get your thoughts...

New templates:
news
news-full
feature
feature-full

template takes options (from Stream model) : 
{ 
item: item,
isLead: true/false, (could have been new templates e.g. news-lead - but there's no difference other than some CSS currently.)
showMedia: true/false //grouping video and image together currently but this may change
}

TODO: 
search result card
FastFT - (if model gets resolved into CAPI model, then no need for fastFT Card)
Sort out small video
