- rework xotcl-core chat machinery to return its responses through JSON and include information about active users - depend on xowiki instead of xotcl-core only - exploit xowiki "Comet" server push implementation when the browser supports it - reduce code duplication - drop plain HTML chat - reduce hardcoded styling - minor cleanups
chat: - remove table-based renderer for polled mode; we use now always (in polled, streaming and scripted-streaming mode) div-based message layout - extend ::xowiki::Chat login by an option "-path" to make sharing of ajax-files simpler in derived packages (e.g. xowf)
