TestCase: add equals() function to QuickTestImageObject.
This allows for comparison of image objects returned from TestCase's
grabImage() function using QImage's operator== function. Doing pixel by
pixel image comparisons in QML is extremely slow.
This functionality is useful for checking that an item was redrawn
after a property change, for example.
[ChangeLog][QuickTest][TestCase] Added equals() function to image
object returned from TestCase's grabImage() function.
