Refreshes the library to be up-to-date.

Hi!

Thanks so much for making this easier for Eclipse users with your project!

I was getting a crasher on the Galaxy when using a photo taken from the back-facing camera due to out-of-memory issues -- turns out the library this is wrapping around is out-of-date, and newer versions have better checks and scaling to prevent this from being a problem.

This pull request updates the sources to what's at HEAD on the `android-crop` library. Hope this helps, let me know if you'd like me to do anything with it :)
