Stop Images from being draggable into text inputs

[GGsource]

Images can currently be dragged onto input for Title and Description, causing the URL to fill in as text. This is fixed for row titles, but the drag icon still appears, it would be better if no indication of accepting images appears.

• Fix title & desc to not receive input from images
• Fix all inputs to not have a draggable icon if holding an image (if possible)
