change sbteclipse version to 2.3.0
Fix missing character and import

The first one was a ')' and the second an import statement. Both caused
a compile error but the second was really hard to spot.
Add withoutPlugins to Java FakeApplication
Fix Enumeratee.mapInputFlatten and Enumerator.unfold to take a ExecutionContext
It was possible for a race condition to occur (see https://github.com/playframework/playframework/pull/1294#commitcomment-3895065).

The issue is fixed by ensuring that only one caller is able to instantiate the client at a time.
Added gzip filter

* Added gzip/gunzip enumeratees, with tests
* Added gzip filter, with tests
* Added two new iteratee concurrent facilities, a joined
  iteratee/enumerator, and a partial run of an enumerator that returns a
  future with the iteratee result and an enumerator that links up to the
  enumerators remaining input.  With tests.
* Documented how to use the gzip filter in Scala and Java, and added it
  to the 2.2 highlights.

Performance optimisations in iteratees and request processing

* Run internal, non-blocking code on the same thread, where possible,
  rather than using a ForkJoinPool. Introduced a trampoline that can
  be used to execute code on the same thread. This is now used instead
  of a fork-join pool for iteratee internal code and when processing
  requests. User code still runs in a separate ExecutionContext.
  For a simple request, calls to the FJP ExecutionContext are reduced
  from about 50 calls down to 2 calls.
* Change some blocking iteratee methods to run in a user-supplied
  ExecutionContext: Enumerator.fromStream, Enumerator.fromFile.
* Optimized several hot iteratee functions: fold, unfold, flatMap,
  Done.mapM, Enumerate.apply.
* Bug fix: removed several accidental uses of Scala's global
  ExecutionContext from iteratees methods.

Fix missing character and import
Add a Junit runner and change the package so that tests are runnable from Eclipse with no change.
Make the samples usable with Eclipse out of the box, by leveraging the JUnitRunner.
Upgraded to latest packager release in order to fix issue #1499.

Also now using the sbt version for build in reference to the external sbt plugins that we include.

asInstanceOf[String] is fragile when compared with toString - it can (and does) cause class cast exceptions.

[doc] Update documentation README to be more accurate

The README was not accurate about the packaging of documentation and how rendering of documentation was done internally.  Added some notes to about the main SBT project and the DocumentationServer.
