Larger map window on the add new point location screen

[rbanick]

The map window on the "add new point location" screen is too small to accurately add points. The interface also doesn't show a marker where the point has been selected. See below screenshot:

Because of this it is essentially mandatory to click Edit Location to load a full screen which shows the point and allows for accurate geolocation.

It would be more sensible to open the full screen in the first place as that's the only realistic way to get a sufficiently accurate point.
