* The reason is to have a consistent approach for Sequence and
TimeBasedUUID, which are both intended as unique event identifiers.
* This means that you can use the offset that is returned in `EventEnvelope`
as the `offset` parameter in a subsequent query.
* speedup ActorCreationPerfSpec
* reduce iterations in ConsistencySpec
* tag SupervisorHierarchySpec as LongRunningTest
* various small speedups and tagging in actor-tests
* speedup expectNoMsg in stream-tests
* tag FramingSpec, and reduce iterations
* speedup QueueSourceSpec
* tag some stream-tests
* reduce iterations in persistence.PerformanceSpec
* reduce iterations in some cluster perf tests
* tag RemoteWatcherSpec
* tag InterpreterStressSpec
* remove LongRunning from ClusterConsistentHashingRouterSpec
* sys property to disable multi-jvm tests in test
* actually disable multi-node tests in validatePullRequest
* doc sbt flags in CONTRIBUTING
* treat snapshot load failure in same way as other recovery failures
* if load of snapshot fails the persistent actor will be stopped, since
we can't assume that a consistent state would be recovered just by
replaying all events, since events may have been deleted
* additional recovery docs
* improve log message
* remove inter-project dependencies between streamTestkit -> peristence -> remote
* make PartitionOutOfBoundsException extend IndexOutOfBoundsException
* some weird formatting
* remove -experimental from HTTP Testkit/Tests
* split out shared LevelDb journal tests into new subproject (not to be
published)
* make the standard queries "single method interfaces" that may be implemented
by a query journal plugin
* remove hints (major problems with varargs anyway), the hints for standard
queries should be given in configuration instead, e.g. refresh-interval
* clarify how to enable the plugin
* added empty class property in fallback config in reference
to have a proper place to document that and throw a more
specific exception if it is not defined
* also some formatting of reference.conf
+ LambdaDoc samples now in the docs project
= simplified internal state by removing recoveryPending
= recovery is now triggered in around* method, so user is free to use
preStart freely - recovery works even if one forgets to call super on
preStart
