Display original geometry of modified and deleted objects #24

Hello!

This is an awesome replacement for OSM History Viewer. Now I'm missing one of its best features: displaying the geometry changes graphically. May I suggest that, when clicking a modified or a deleted item, not only tag changes but also geometry changes get displayed? The old shape/position might be marked in red or perhaps purple or any other color that is unusual in the most common map color schemes (Mapnik/Cycling/Tranport/Mapbox).

If this turns out tricky to implement, then at least display some message or icon indicating that geometry was changed (sometimes only tags got changed).

Thanks for the feedback. Old geometry is in the database and it can be displayed, I will add this feature.
