Don't panic with long URLs and don't give your private URLs any more to shortening services!
A new script urlserver.py has been added. This script shortens URLs displayed and serve them using own HTTP server, which can be used to display a list of all URLs as well.

Many options are available to customize shortening of URLs, display in WeeChat and HTML page (see /help urlserver and /set plugins.var.python.urlserver.*).

The URLs are saved into ~/.weechat/urlserver_list.txt when script is unloaded, so that URLs are persistent when you restart WeeChat.
