ScriptConsole: Move from Debugger to QmlJSTools
The console is now a part of qmljstools plugin. The console appears as an output pane. A dummy QScriptEngine evaluates expressions when a declarative debug session is not in progress. During a debug session, the expressions are evaluated by the debug services.
