>> Description:

TM Make plenty of pointless changes to their site.
Previously when you are viewing an action listing, the path to the catagory the auction
is listed in is displayed as a link form just above the auction title.

EX.:  Home > Computers > Desktops > No monitor

clicking any part of the link would have taken you to the associated catagory directory.

With the new change, if you click on an auction link from within a members listing pages, the
catagory links from that auction listing will only display auctions from that
particular member not all members as it used to do.

EX:  MembersName > Computers > Desktops > No monitor

This stupid change has annoyed me long enough to create this greasememonkey script.
Instead of replacing the members only catagory path, it creates another link below it
containing the normal full path.

This script will not run on following catagories as they are not effected by this change

(1) Trade Me Jobs
(2) Trade Me Property
(3) Trade Me Property
(4) Movies-TV
