Check the naming of the Easing Curve Editor and the Animation Curve Editor

Now that the Qt Design Studio contains both an Easing Curve Editor and an Animation Curve Editor, it is important to name them accordingly. Currently, the "Curve Picker" icon opens a dialog with the title "Easing Curve Editor". It should be renamed "Curve Picker". Or something else that is used both for the icon and the dialog.

The dialog opened by the "Curve Editor" icon currently has the title "Qt Design Studio". It should be renamed "Curve Editor". Or something else that is also used for the icon.
