* Check photo & camera perms and alert the user if not available (close #64) - Adds perms checks with a prompt to update settings if needed - Moves initial access of photos in the composer so that the initial prompt occurs at an intuitive time. * Add react-native-permissions test mock * Fix issue causing multiple access requests * Use longer var names * Update podfile.lock * Lint fix * Move photo perm request in composer to the gallery btn instead of when the carousel is opened
