Package build tool does not detect binary file changes

The package.php tool does not detect binary file changes. So changed image files are not in update packages. This is caused by a regular expression that does not match directory names like release-3.0.8 because it does not allow dots.

preg_match('/^Binary files ' . $package_name . '\/(.*) and [a-z0-9_-]+\/\1 differ/i', $line, $match)
