Added Private Eye.

The `.pkg` installs `/Applications/Private Eye.app` and `/Library/LaunchDaemons/com.radiosilenceapp.nke.PrivateEye.plist`.

The uninstall process can unload+remove the `kext` just fine, but runs into permission errors when removing the app:

> ==> Running uninstall process for private-eye; your password may be necessary.
> ==> Unloading kernel extension com.radiosilenceapp.nke.PrivateEye
> Error: Permission denied - /Applications/Private Eye.app/Contents/Resources/Private Eye.kext/Contents/Resources/en.lproj

It's happening for me even after nuking and reinstalling. There is no uninstall script, so I'm not sure what to do.
