v17 - Now supports closed-source copyrighted Google Play Location Services (aka GMS) if available, else falls back to the old-style Android Open Source Project way of doing things.

This is a beta release of this functionality - please don't use it in production apps yet - but do please help me test it. Once it's all good, I'll release v18 including Gradle and Maven support.
