change sbteclipse version to 2.3.0

The first one was a ')' and the second an import statement. Both caused
a compile error but the second was really hard to spot.

[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.
Don't lose echo when initialising Play project settings

"play-interaction-mode" was recently introduced as a setting for Play
projects. The setting object was initialised when a Play project is
created. Unfortunately, initialising the setting object created a
JLine ConsoleReader object which, as a side-effect, disabled terminal
echo. Instead of creating a ConsoleReader at initialisation time, we
need to delay creation of the ConsoleReader until the setting object is
actually used, so echo can be restored afterwards.

Made Global handlers return futures

The results refactoring ended with Global handlers, such as onError,
onHandlerNotFound etc, returning SimpleResult, which meant they couldn't
be asynchronous.  This changes the type to Future[SimpleResult].

Also extracted code samples out of Java Global docs, and updated all
docs for this.
