I added the $Id:$ tag to all files; this is a mechanism that CVS
follows to add the version information in each file. The ID's are in
HTML comments too, so they will show in the page source of all Wiki
pages, which might help debugging.

git-svn-id: svn://svn.code.sf.net/p/phpwiki/code/trunk@25 96ab9672-09ca-45d6-a79d-3d69d39ca109
