Modified AppCommander.requestReceived() to use new style URLs and
App.handleLogicalRequest(), rather than using BladerunnerUri to convert
the old style URLs so we can use BundlableNode.handleLogicalRequest().
Simplified spec tests that aren't specifically testing app handling of
logical URLs to go directly via the bundlable node instead.
All but one of the war integration tests now working.
Deleted the now defunct BladeRunnerUri and WarCommand classes, and all
related classes and methods, and updated the RestApiService to use the
model directly instead of using the old WarCommand.
