Subject: Update links color/weight between mirrors depending on source and
 bandwidth.

 * the bigger the bandwidth available, the larger the link.
 * red links from source to Tier1 servers, blue otherwise.

Could be improved (link weight depends on mirroring server output capacity,
not on actual link capacity between this mirror and source mirror).

Could be good to have distinct icons for source, Tier1 and Tier2 mirrors
(not sure how to do that in JS, maybe using KML instead?).
