Peter Kokot be49d61b19 Remove old SVN keywords substitutions
When the PHP source code was versioned in Subversion, there was
possible to substitute certain keywords such as $Id$ with revision
number, last change time and author name. Such approach is not used
in Git so this patch removes these outdated artifacts from source
code files.
