Ability to resize images.

[woj1993]

I would want to propose possible fix for #70 and enchantment feature that I would want to see.
It it ability to resize screenshot that we took.
It's pros are:
-we can compare elements that really changed in size.
-we can use Java image manipulation functions
-we wouldn't need to rewrite comparison algorithm which might be harder.
Cons:
-it's more code to menage
-we would dependent on Java image manipulation functions
-it would take some time to resize image.

I imagine it would be a method something like this .resizeImage(newHeight,newWidth,algoritm)

Please give your opinion about this idea here.
