Updates the project to match the AE5 version.

Fixes the legends and adds instant inspection although this approach is somewhat ugly.

I think the following can be removed, no? I don't see where it is used

def convert(x):
    try:
        return int(x)
    except:
        return 0

Is there a workaround or alternative for getting the images from marinetraffic website? Looks like they are now blocking programmatic access now

[droumis]

I removed the unnecessary code.
I will file an issue about the restricted access to the image data.

will merge as-is now
