iOS 10 permission text needed

[ahmetws]

with iOS 10 additional texts needed for the permissions. The library uses the following two:

<key>NSCameraUsageDescription</key>
<string>App uses permission to take photo and add it to feedback screen</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>App uses permission to add photo to feedback screen</string>

The app crashes when additional photo cell tapped on the library unless this parameters added to project Info.plist

I believe that some kind of warning or assert needs to be added to this lib to warn a developer about this and avoid crashes.
