Title: viewer: show more exception messages

When trying to render the map widget in the viewer, we catch exceptions
and print out the message to stderr. The only exceptions that are printed
are mapnik::config_error messages. mapnik can throw more errors, so this
change makes it catch all std::exceptions.
