Arquillian Cruiser: Expand All button

Using the Arquillian Cruiser view is a way to get a quick overview of the current deployments and their content, but that point is semi lost in the levels of clicking required to get the overview.

Project -> SourceFolder -> Package -> TestClass -> Deployment -> X

First on level X are you getting to the real content, and even then you probably have to go another N levels via the archive package structure to see something real.

The view has a CollapseAll but is missing a ExpandAll action.

Due to the possible node size we might not want to Expand all the way to the bottom, but perhaps down to the Deployment level when using the 'ActionBar' ExpandAll action. We could add a Context Menu Action to the Deployment that would "ExpandAll of Content" to split it in two moves if needed.
