Facia tool snaps

# What?

__Step1:__ Snaps. We can now drag elements into the fronts tool, with a few URL parameters, that will then create a story displayed on the fronts that are not from the content API.

__Step2:__ We then progressively enhance these elements with JS, if required, with the `data-snap-uri` attribute and fill it with the nownewandamazing content. i.e. Football tables.

This allows editors to choose which automated content they feel is relevant and where to put it.
The first tool to create these URLs will be the Football tool which will have a PR open soon.

# Notes
* Due to the complexity of the facia frontend, we have this behind a switch and will be testing it on code before anyone can get their mits on it.
* Apologies for the commits, this was the lovechild of a branch that was never meant to make it to the public eye.
