Move QmlConsole to Debugger
Now it is closer to its only user and possibly reusable for no-QML uses there. We also drop the QML/JS syntax checker. The application being debugged can already tell us about syntax errors. There is no need to duplicate that functionality. Change-Id: I2ba151f9f4c854c6119ba5462c21be40bddcebf9 Reviewed-by: Ulf Hermann <ulf.hermann@theqtcompany.com> Reviewed-by: hjk <hjk@theqtcompany.com>
