Editor widget colors too similar to editor backgound in light theme

[LawrenceLiu023]

I was using Monokai Pro v2.0.1 light theme, and noticed that the colours of editor widget background and border are too similar to the colour of editor background. This makes it a little difficult to distinguish the widget contents from the editor contents. It would be helpful to adjust the colours for properties such as "editorWidget.background" and "editorWidget.border".
