Allan found a few issues with the new per-app location settings:

Spacing is off inside the dialog:
    * Add 12px margin-bottom to location-vbox
    * Add 12px margin to location_dialog

"Location Services" label isn't vertically centered inside the list row.

Some comments about the long description string ("Location services allow applications to determine your geographical position. Accuracy is increased by enabling WiFi and GPS."):
    * "WiFi" should be "Wi-Fi" * We don't ever expose "GPS" as a thing, do we?
    * "enabling" is a sucky word. The second sentence also implies that they are turned off.
    * "determine" is sucky.

So maybe something like:"Location services allow applications to know your location. Using Wi-Fi and GPS increases accuracy."
