[PATCH] ui-summary.c: Move urls variable into print_urls()

[Lukas Fleischer]

There's no need for this variable to be global. Printing the header in
print_urls() instead of print_url() allows for moving this variable into
print_urls() without having to pass any status to print_url().

Note that this only works as long as we don't call print_urls() more
than once.

I am aware of the "columns" code duplication caused by the last two
patches. In order to keep commits atomic, I will deal with those in an
upcoming patch set.
