Close the connection to the EventSource before leaving the page

Some browsers such as current Firefox may complain otherwise

Chat reform

The goal of these changes is to reduce the "mode" specific javascript code in the chat implementation and reduce server-side guessing of browser capabilities.

- In the MessageRelay class from xotcl-core, we rework the javascript code sent to the connection when doing scripted streaming to make less assumptions about the functions defined in the parent scope

- In the chat code from xowiki, we move most of the logics to guess the mode into javascript, where we can test the actual capabilities of the browser without relying on the user agent

- The previously 4 javascript files dependant on the chat mode have been made into one

When the mode is "streaming", use Server Sent Events instead of a "plain" endless request

This has the advantage of a clearer, less hacky api, which, for instance, does not require manual parsing of the partial response.

Fix idiom

- make sure the anonymous users nsv is created when the chat is instantiated

- make sure xo::cc is available when the anonymous identifier is generated

- handle in the Chat package, that the uid may not be a user, but an IP address

- adapt other chat skins to the new anonymous user logics

Added support for anonymous users in chat class

Previous version of the chat class required a login for participating

in the chat. The new version also supports a mixed mode, with

authenticated and non-authenticated users can participate. For

unauthenticated users, the disambiguation is performed over the peer

IP address, similar to the xotcl-request-monitor. Instead of the raw

IP address, an artificial username is displayed for such users (like

e.g. userXXX).

For unauthenticated users, some differences apply:

- one cannot provide a link to the private page

- unauthenticated users cannot access the user-portrait

of authenticated users.

The GUI changes are only made on chat-skins/chat-classic.js, not on

the other skins.

Do not add additional style around the chat includelet, regardless if this is a "chat_room" or a "chat"

Fixes and adjustments for the chat-minimal chat skin:

- show the fullscreen button, very useful on devices with little screen real estate

- display on the same line, in respective order, avatar (when enabled), user name and link, timestamp and message

- wrap the message over multiple lines when it would not fit

Improve responsiveness at smaller resolutions for the fullscreen button

Styling changes for minimal setups

This change is necessary for minimal setups, e.g. for plain installs

during regression test, when no bootstrap packages are available.

- define yui as last-resort fallback for "toolkit"

- handle CSS class composition for YUI as well

(merge of class-specific and item specific CSS classes,

used for color management for publish status button)

- remove underline for publish-status in YUI mode
