Crash and memory leaks

[kirmakarenko]

1. While working with this library sometimes I face some crashes. Crash is happening when I try to pick photo from library. It happens inside synchronizeAssets function. sortedAlbumsArray is empty and section is equal to 1. See screenshot below:
   
   I set up AssetsPickerViewController in my button IBAction function like this:
   
2. When I inspect memory usage, I see some memory leaks if I'm not mistaken.
   
3. And last thing, when I select images and click done, they are being duplicated to gallery. Is there a way to prevent this?

Thanks!

Fixed second issue in new version, and I think I have to investigate more for the first one.
