Post Detail Header Action Buttons

* Adjusted the layout.
* Made room for a longer title.
Leaflet Attribution

Moved the Leaflet attribution text to the footer.

Trying to remove it via MapView.js using `prefix : false` but it is not working. I also tried `grunt build`

in `MapView.js`

```
map = this.map = L.map(this.$('#map')[0], {
	center : new L.LatLng(-36.85, 174.78),
	zoom : 5,
	layers : [minimal],
	scrollWheelZoom : false,
	prefix : false
});
```
