Added .springBeans (Eclipse Spring IDE generated file) to .gitignore.
Modified the Maven scope of slf4j-simple to only be for test.
In the annotation event sink, add logic to allow wrapped exceptions of
type ReplaceHandlerException to be unwrapped and thrown rather than
being rewrapped and thrown.  This allows, for example, a
NonResettingRestartException to be thrown from an event handler and
things work as expected.
Removed the scope on the slf4j-simple dependency -- missed the fact that
it is set in core.
Removed unnecessary instanceof check.
Added Javadoc to test case with a link to the pull request.
Merge pull request #353 from ageery/wicket-6.x
