refresh VFS on map change instead of restarting VFS, fix #105

Neumond probably thoughts it would be cool to make a file observer
that reloads the VFS each time the map change, was a nice idea.
Badly, it makes the VFS reloading itself before saving a map,
losing the current work done.

Hopefull, since I added a “Refresh” ability that refreshes the VFS
without reloading the map, we can just use that Regresh ability
instead.
