Jonathan Druart b678301e46 Bug 13684: C4::Budgets should not be used in C4::Output
Bug 12844 removed the call to C4::Budgets::GetCurrency.
The use of this module can be completely removed from C4::Output.

Signed-off-by: Tomas Cohen Arazi <tomascohen@gmail.com>
It makes sense and no runtime errors found.

pagination_bar($base_url, $nb_pages, $current_page, $startfrom_name)
Build an HTML pagination bar based on the number of page to display, the
current page and the url to give to each page link.
C<$base_url> is the URL for each page link. The
C<$startfrom_name>=page_number is added at the end of the each URL.
C<$nb_pages> is the total number of pages available.
C<$current_page> is the current page number. This page number won't become a
link.
This function returns HTML, without any language dependency.

=item output_with_http_headers
&output_with_http_headers($query, $cookie, $data, $content_type[, $status[, $extra_options]])
Outputs $data with the appropriate HTTP headers,
the authentication cookie $cookie and a Content-Type specified in
$content_type.
If applicable, $cookie can be undef, and it will not be sent.
$content_type is one of the following: 'html', 'js', 'json', 'xml', 'rss', or 'atom'.
$status is an HTTP status message, like '403 Authentication Required'. It defaults to '200 OK'.
$extra_options is hashref. If the key 'force_no_caching' is present and has
a true value, the HTTP headers include directives to force there to be no
caching whatsoever.
