[lively-kernel] Lively repository version system: How to find out what version I am running?

http://lively-kernel.org/repository/webwerkstatt/ points to a single SVN repository. Whenever you visit a page there you will automatically access the HEAD revision of that repository.

Exception #1: You can access older revisions using a special URL scheme. For example http://lively-kernel.org/repository/webwerkstatt/!svn/bc/10000/webwerkstatt.xhtml shows you webwerkstatt.xhtml at revision 10000. Also, all other files that are used to run this world are of the same revision (source code, etc). This allows you to go back in time. We have several tools in our system that allow you easy access to older versions without the need to remember the URL scheme.

Exception #2: Sometimes the browser caches old versions of xhtml pages. We are pretty good now to load new versions of js files whenever that is necessary but depending on your web browser xhtml files are not always in their most current version. Simply reloading a world will fix this.
