[IMP] im_livechat: visitor history command

this commit introduces the '/history' command
for an operator during a livechat session.

When the visitor load a page, its url is added in
a cookie (kept only 1 day) in order to track his
visited web pages.
The '/history' command will ask the cookie content
and send it to the operator as a transient message
in the livechat channel.
