No-aar update

Hello, I'm back from the field and it's time to update this library.

CHANGELOG for 2.5.2:

• Removed the .aar file from PR #23 by @mikehardy . Instead, it now uses the source directly from original repository. By this way, I think it's easier to debug, to control and to add new features from now on. Thanks a lot!
• Updated guide for RN below and above 0.60 linking.
• Removed SYSTEM_ALERT_WINDOW flag. It should not affect anything anyway.

Summer 2018 release: Dropping support for RN 0.47 and below

And yeah, you should step-up your project too.
