Like AppCommander, WorkbenchCommander now also makes it possible to
direct content plug-in requests directly at the workbench.
There is now a BundlableNodeBuilder.hasReceivedRequest() method to go
along with the AppBuilder.hasReceivedRequest() method, so that we can
route requests directly through to the aspect or workbench except for
cases when we're actually trying to test the logical handling of request
paths to the app.
Fixed a bug that prevented requests for non-defualt aspects, and created
the first tests of what will become a new test suite for this area of
code.
Renamed IntegrationWarCommandTest to ServedWarTest now that it is a test
of the model, rather than a test of the now deleted 'war' command.
