Revert breaking constructor change introduced in 1.3.0

[jfahrenkrug]

Revert breaking constructor change introduced in 1.3.0. This changes the default EasyImageView constructor back to accepting an ImageProvider instead of a Widget. Constructing an EasyImageView with a widget can be done by using a new named constructor: EasyImageView.imageWidget.

Thank you to @wferem1 for reporting this.
