- Provided new interfaces for akka-persistence to be usable directly through ReceiveBuilder/PartialFunction. Added a sample java project to showcase the usage of these API's with akka-persistence. - Fixed a minor comment block in javadoc code snippet. - Renamed java event persistor and fixed a documentation typo. - Put back java event persistence methods in UntypedEventsourcedProcessor and copied them into AbstractEventsourcedProcessor for the sake of clarity in javadocs. Also corrected some doc punctuations. - Documentation for akka-persistence java 8 lambda expressions support. - Moved code examples referred from within lambda-persistence.rst to java8 compatible sample project. - Removed remaining unwanted java8 compatible source files.
