New image utilities widget

[TimMonko]

Considerably simplify the UI of the Image Utilities widget.
In actuality, this adds many features, consolidates methods, and provides a cleaner, easier to use interface for the user.
The widget is now scrollable, and includes dropdowns with options.

In the future, I will also add the ability to save images as figure-types.
