Updated release date for "Akka Concurrency" and "Akka in Action" release date estimate, and added references to two books, "Effective Akka" and "Developing an Akka Edge".
* Numerous version upgrades to dependencies
* Publish integration test maven dependencies automatically
* Use slf4j logging, with standard OPS4j Pax Logging
* Maven and sbt use different target directories
* Add a custom serializer to the integration test
* Add akka-persistence to the integration test
* Removing reference copying and using a BundleDelegatingClassLoader
* Make akka-actor a proper bundle, and remove duplicate classes and
reference.conf files from akka-osgi
* Remove akka-osgi-aries
This is a hackathon team effort by:
* Björn Antonsson
* Endre Sándor Varga
* Roland Kuhn
* Patrik Nordwall
The idea is to filter the sources, replacing @<var>@ occurrences with
the mapping for <var> (which is currently hard-coded). @@ -> @. In order
to make this work, I had to move the doc sources one directory down
(into akka-docs/rst) so that the filtered result could be in a sibling
directory so that relative links (to _sphinx plugins or real code) would
continue to work.
While I was at it I also changed it so that WARNINGs and ERRORs are not
swallowed into the debug dump anymore but printed at [warn] level
(minimum).
One piece of fallout is that the (online) html build is now run after
the normal one, not in parallel.
