Frontend-GNOME-IRC: add context menus to treeview node too

The context menus for IrcPersonChatView were only added for when the
user right clicks on the chat area, but not when the user right-clicks
on the treeview child element. Now they are added to both, and with no
code duplication.

manually.

Also, add Unicode support (decimal XML character escapes).
[Engine-VBulletinChatbox] Fix /relogin and /retoken.

* /retoken shouldn't request the security token twice.
* /relogin should request a new security token after login.
[Engine-VBulletinChatbox] Highlight my own nickname.

A bit weird that this is done completely manually in each protocol.

Now output with every relogin or retoken operation, with less copy-paste!
[Engine-VBulletinChatbox] Don't prepend event prefix to commands header.

It unwittingly survived a restructuring...
[Engine-VBulletinChatbox] Fetch security token from FAQ page.

The chatbox archive is a notoriously slow page. The FAQ page seems to be
the most efficient page in terms of processing power, although the data
itself is extracted from the global search form.
