Version 0.2.9

This release has been brought to you by the hard work of @apjanke and @psmagin. Here is a overview of what is landing in this release:

• The PlaceDetails.Review result now has profilePhotoUrl and relativeTimeDescription.
• There are a bucket load of newly added AddressComponentTypes, including continent.
• Some new AddressTypes, also including continent.
• The DirectionsApiRequest javadoc is much improved.
• The code has been updated from it's ~1.5 era roots to modern Java.
• PlaceDetails now return an array of AddressType instead of String.
• OkHttpRequestHandler evicts threads from it's connectionPool to better handle situations where there are multiple GeoApiContexts. Please note, having multiple contexts will mean that rate limiting won't work properly, so don't do this unless you really know what you are doing.
• GeocodingResult and PlaceDetails gained support for returned PlusCodes.
• All the model objects gained much more informative toString() implementations to aid in debugging.
• OkHttpRequestHandler.Builder now exposes the underlying OkHttpClient.Builder to enable advanced customisation, like setting Proxy settings and the like.
