PrivacyGuard: Specify a default value in Settings.getInt method call
* While privacy guard is enabled by default, the default value specified
  here is returned only when the setting is not defined or not an integer.

PrivacyGuard: confirm permissions reset
The button to reset all application permissions to enabled looks
suspiciously like a refresh button. Prompt the user with a confirmation
dialog to make sure they know what they've pressed.
