Since the character creator now produces a builder object with things
like the name included, we no longer need to have a duplicate copy of
the character's name (it was needed because the name lived inside the
anonymous function, and thus wasn't accessible).

Now that we're self-hosted, we can have all the smut we want!

Entities now have their templates cloned (by serializing and parsing) to allow for
a single object to be passed in repeatedly.

It was an array, for some reason

This is handled as part of the attribution data now. It was unused
for quite some time, but I kept adding 'em anyway!

displayEntity() now only triggers a refresh of the world if asked, and
the scale is only redrawn if the world's size has changed

Also remove a spurious info file for countries

This also updates the attribution system so that entire folders can be covered
by a single entry. It assumes every file has the same source.
