Release 8.4.0

Release 8.4.0 contains significant changes, the most notable addition is the spf4j-slf4j-test logging backend, you can learn more about it at: http://www.spf4j.org/spf4j-slf4j-test/index.html . This module is not being used by spf4j for improved testing and contributed to the discovery of several bugs that have been fixed in this release.

Other important changes are the introduction of the ExecutionContext which is the basis of passing around context baggage (deadline, tracing, etc...).

This release also drops the use of joda-time and switches completely to jdk 1.8 time.

other than that a lot of timing calculations have been switched from System.currentTimeMillis to System.nanoTime.
