Popup menu link paths don't implement PURL's path prefix

I am using PURL on a site which uses the popup module's menu blocks, but links that should display with a path prefix, don't.

Looking at the code, it appears that a popup menu item's links are not created using the l or url functions, which would enable PURL to act on the links (it uses custom_url_rewrite_outbound to modify them, based on information provided in the $options array). So if we create the link paths using the url function and pass $item['link']['localized_options'] as the $options parameter, in processing.inc, the path prefixes are placed in front of the links (line 157):

    $link_path = url(str_replace('%', $user->uid, $item['link']['link_path']), $item['link']['localized_options']);

I don't know the module well enough to know if this is the best place for it, but it works for my purposes.

I'll create a patch shortly.
