 * Add unit test
 * Do not depend on magic error codes to decide whether we see an

QmlDesigner is not needed anymore for the QuickToolBar
QmlJSEditor has a depends now on libs/qmleditorwidgets

QuickToolBar is moved to QmlJsEditor

For some widgets and resources QmlDesigner relies now on
lib/qmleditorwidgets

The library qmleditorwidgets contains widgets and image resources

This library is created to make QuickToolBar independent from
QmlDesigner plugin.

All the widgets I moved to qmleditorwidgets are removed from
QmlDesigner in this patch

engine.
