- 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
move all hardcoded styling to the adp template, which might be styled by the theme. Also, biring some order in the login proc, e.g. don't open and read a file to include a javascript all the time.
