Location toggle filters

When the card grid module is used - the location toggle filters will be added above.

If at least one card in the grid has a location tag (location:XXX where XXX is the location name) - a toggle filter button will be added.

Nationwide is the default and will display all cards.

NOTE: These toggles are currently single-select. If the client wants them to be multi-select, a For Purpose developer will be required to make a change.
